I recently sold a phone on eBay as a BIN with best offer, received an offer and accepted, they received the phone this morning but then recieve this message :

The phone is not unlocked as stated in your description, can i return for a refund.

I looked at my item description and under item specifics under simlock it says T-Mobile, also in the description that i wrote i said locked to T-Mobile, but after selecting the phone for eBay to fill the details right at the top it says unlocked !!

I said i wouldn't have a problem with issuing a refund, but now they are asking for me to pay for return postage, i refused as it is not in eBay rules (as far as i am aware)

Would you pay for return postage ?
