I have sold a brand new anti virus software sealed in the box.
My buyer is claiming he can't install it and has called Norton for advice and they could not help him, he wants to return it for a refund.
I think he has just copied it and is trying to pull a fly one.
Where do I stand as a seller, he has damaged it by opening it so it is not in the same condition as when it was sent, also will I have to pay him a refund including postage plus postage to send it back to me?
Am very angry as I just know he is taking the p*
Please help with advice?
