Buyer asking for refund

[rollcy]

I sold digital product for my client. And 1 month later he ask for the refund, because his account was banned. I dont want to refund. I dont see any mistake from my part. And after 1 month is unfair to ask for refund. I hope ebay wont accept this.

I hope ebay wont accept this.

Has the buyer filed a return case against you, or just "asking" for a refund in the message?
