i requested a return label and they sent it but the day after i got an email saying they recieved the item and are processing my refund. i didnt even send it back. what should i do? do you think the refund will go through cause they think i sent it?

Very strange.

Given they've somehow established you've returned It, play along with It and allow them to refund you. If there's any dispute later down the track, It's no fault of your own.
