Not gonna use OP service. No answer on several e-mails since 1 week back. Bad customer service.
We have responded to your e-mail.
The trade was created 4th December. You sent a single small deposit and miscalculated on transaction fees and want it returned.
Transactions fees have been so high recently, at one point going above 400 sat/vb, that it would cost us the same amount in Transaction Fees, just to send this back to you.
As a good will gesture, we have extended and extended this trade for you. It remains open, if you send the remaining balance, it will complete as expected.
