I said above that you had to refund, you chose to upgrade it anyway, if he has no use for it now because he refunded his customer, you will have to refund him either way. Not sure why you thought my decision was a question but it was not.
I'm ready to refund; it's not an ISSUE for me. But what's the reason behind the refund? So You've got an Upgrade service. I ordered an upgrade, and then I gave the wrong credentials, expected the time to pass, and then asked for a refund because "I REFUNDED THE CLIENT WITHOUT TELLING YOU"? Thanks.
Also let me know if I'm liable to create an account for him or not. Thankyou!
