How to get rid of a customer on Upwork?

Question

Upwork

Hey!
Got an idiot customer, now I don't know how to get rid of him.
The work was done, the contract was closed, then there was a dispute, which was also closed, they gave me the money, he confirmed that everything was done.
Now for 2 weeks now, he says that there are some problems in my work. Naturally, there are no problems, he wants me to do additional work for free.
He took a lot of my time, I already regretted a hundred times that I contacted him, I should have immediately made a refund.
I blocked him a couple of days ago. And today support wrote me. They say that the client says that there are problems in that job, and they tell me to talk to him.
The question is what to do? How can I get rid of this idiot? What could be the consequences? What to say to the support?
UPD. By the phrase, took me a lot of time, I meant that during this time I tried to do everything that was possible, nothing helped. At first I did the finishing touches, then I made more finishing touches while there was a dispute.
Our communication takes place every day approximately according to this cycle with slight variations.
1. He writes to me that he has found a mistake in my work.
2. I check the work again, I say no, it's not my fault.
3. He asks why.
4. 10-20 posts why it's not my fault.
5. He speaks well, but this must be done in such and such a way.
6. I say well, it will cost so much.
7. He says that it is very expensive, asks if I can do it 3 times cheaper, asks to explain why it is so expensive.
8. 10-20 messages I explain why it costs so much.
9. He says okay. Further or says that he needs to think. Or simply does not write anything for half a day. Sometimes he asks if I did what he asked. The contract was closed a month ago, the dispute was closed 2 weeks ago.
10. Next, see point 1.
All this, of course, takes a lot of time. Lots of other work.
Is it possible to make a refund on an already closed contract? (and still pay extra to fall behind :)). Will this get me out of contact with him? Will support continue to respond to his letters?
Thank you.

Answer 1

If the volume of finishing touches is trifling, spit, finish and renounce such customers in the future.
If there are A LOT of finishing touches (and they obviously were not part of what you were supposed to do) - let him create an additional one. work and agree on the points of the amount of finishing touches. So that in this case, you can easily prove that everything agreed is fulfilled. All correspondence in the upwork chat. All the nuances of the work are discussed in all details.
The consequences, alas, can be anything. For example, you may get a low grade, and this is a serious problem for further work. I'm afraid that no one is safe from such a rake.

Answer 2

Also in a year there are 1-2 such customers, my work algorithm is as follows:
1. Never agree to additional improvements if this is not included in the TOR. Right from the very first list of edits from him, you need to divide this list into two parts: real bugs that I fix for free and new improvements that will be included in the next milestone.
2. If the client insists on your free work, then once in detail with examples explain to him the difference between bugs and tasks not included in the TOR.
3. If the client continues to whine, I simply copy the same message to him.
4. If the client is completely stubborn, I write to him that I will send a complaint to Upwork, as he asks you for free work.
5. To all sorts of pleas that he has a tight budget and he has already spent it, write that you understand him and you are very sorry, but you do not work for free.
However, this all works very well, only if at the first stage you made a clear TOR, if you were too lazy to work on the TOR and accepted some general description from the client, then the matter of course becomes more complicated, the main thing is to be adamant and consistent. And if you first, out of the kindness of your soul, do something for free, then another, and then get angry and ignore the client, then this is the worst thing.
In this case, I recommend that you be patient, once again explain in detail that you do not work for free, what is a bug, and what are new tasks. Send him a detailed list of your completed improvements, where it will be described point by point what exactly was a bug and what was additional work (you can even estimate them by cost) that you completed for free. If there are any bugs, then fix them all the same, and all new tasks can be estimated at a double or triple rate, say that you are currently busy with another project, maybe you will be free in a month. If everything suits him, let him send a new offer in a month, if not, then there are many other freelancers on the exchange.
And repeat this message until he gets bored.

Answer 3

Try starting the approval process for a new job and overcharging your services. You can try to get him to change his mind.

Answer 4

Solve the issue through upwork support. The customer confirmed that the work on the TOR was completed in full and the contract was closed. What the customer wants now is his problem. Any finishing touches through the contract. Raise a question to the support about blocking the customer's account

Answer 5

Now for 2 weeks now, he says that there are some problems in my work. Naturally, there are no problems, he wants me to do additional work for free.

Consider another question:
He wants to pay you extra for improvements.
Negotiate the price, open a new job on Upwork and go.

Answer 6

In a similar case, I told a client that I would only do his projects post factum fixed price. Those. I do whatever he wants and say, it took so much time and it will cost so much. I agree - open a fixed price project (and in this case upwork guarantees full payment), I don't agree - go to hell. No correspondence why this is so, and not otherwise.
