Problem issue partial refund to buyer

[zapgone]

I'm try to issue partial refund for shipping cost to buyer but keep get email unable to process refund.

There was a technical issue and we couldn't process the refund you sent. We apologize for the inconvenience. Please retry sending the refund, and we'll get it to the buyer as soon as possible.

I retry since yesterday and today more than 10 retry but get same message. 

Just wonder if other seller having the same problem.

I'm having the same issue, going on 3 days now.  Support told me to wait 24 hours and try again.  Failed again.  Clearly they have no idea how to resolve this.
