Where to leave feedback about the customer / intermediary?

Question

Freelance

This is the first time in the last three years.
Refusal to pay the second half for work. After that, a block for messaging on freelance and Skype.
Actually the conflict is settled after a couple of hours
I climbed onto the landing page of the agency through the order form sent a message: such content

Not paying for the work performed ...., in the amount of 50% of the agreed amount. After that, he was blocked on Skype, the connection was through .... project manager. Due to non-payment, a review of non-payment will be published indicating the details of the agency. All the best.

I received a response from the director of this agency that the payment would be made, there was an attempt to answer me with approximately the same move in the form of blackmail with a hint of incompetence (here I apparently should have been blown away?)) to which I agreed with the condition that I would attach a screenshot with all the correspondence and t3, after reading the screenshot, they changed their minds (it is clear that everything is OK on my part), in response I received

Translated. No comments about work.

After some waiting, the money never came, usually within 5 minutes they come. Unsubscribed that he did not receive payment and asked for a screenshot of the payment. An hour passed and a screenshot came with a time difference of 4 minutes from the current one, I hope it's just a time difference, but who knows.
Here are such businessmen) situevina, of course, from the category of anomalies for 6-7 years of work, the eye was swept up on those who might not pay, and in this case they had real contacts and links open, with positive reviews, and the landing page had a positive face, and they themselves went out in this case, you simply don’t expect a dirty trick and such audacity in the form of “the client will not pay” on me.
I think almost all commentators would simply score in this situation.

Kill it, just kill it.
If you were thrown only 1 time in 3 years, then this is just an excellent result.

The same place where I ordered.
