Odesk: is it possible to make a refund without damaging the rating?

Question

Freelance

The first contract for odesk has been tracked for 12 hours so far, but I realized that I don’t want to work on the project further for various reasons (the client gives very vague requirements, changes them, rarely gets in touch, and also sets unrealistic deadlines).
If I make a full refund of all watches before it's too late (I don't know if 10% odesk fee will be included here or not, but still) and complete the contract, will he be able to give a bad rating or review?

Answer 1

Sorry for the necrophilia to the post. It’s better to agree right away that you don’t like the deadlines, you shouldn’t quarrel, everything can be settled without conflict. I had clients, I just politely explained the situation.
Yes, he can give you a bad review, but this is not beneficial for the client either, because. no sane freelancer would take a job from a client who gives bad grades.
You can cancel the hours until the work week is over, you can try to close the contract, but I have not tried this method.
