Thanks for all your replies. To put his into perspective, it's a Discogs purchase from the USA, and after receiving the record to find it has an edge warp plus writing on cover and label (not mentioned) I check his feedback which is dire, loads of recent negs advising 'avoid', 'scammer', 'worst experience' I decided to work it out via the dispute process immediately (not claim). I would usually message the seller first to work things out, but considering things this seemed the safer option.
My message back is from someone who is working for the seller and is clearly not up to the job, he has also been grading the items. He suggests a part refund and keep to the record which I denied, instead opting to return it for a full refund (he's offered to pay my return postage, great!)
I advised it must be returned tracked as PayPal will want to know it's got back safely and can be verified online. The seller comes back to me saying its a 'hassle' having to sign!! I ask for a confirmation of return address, three days and no response, so this morning I raised it to a PayPal dispute for the full amount advising that I would be happy to return the item so long as the seller covers costs. I will update with progress.
