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.
OK, thanks for answering. You can close the transaction and keep the BTC as a donation. Fees high at the moment.
