Recently, I got an order (from a buyer who has no previous reviews). I trusted him and sent him a custom offer (with unlimited revisions) and started doing an order.
I have delivered the order, and now he is asking for revisions (without mentioning any requirements or errors, he wants).
But, when I asked him about the errors (he is talking about them), he requested to cancel the order, stating that I am unable to handle the order and correct the errors.
However, I have canceled the request. But, now I am worried about the order.
What to do? How to handle this buyer?
