I sold my iPad mini, it had a broken screen where it had been dropped twice, general wear from being used and i gave a detailed description along with plenty of pictures showing everything.
I stated collection only as i wanted cash on collection because it was broken i didn't want any scammers or Paypal problems and thought that would get rid of all the obvious scammers if it was only for pick up.
Any way auction ends and it sells for £128. Then the guy messages me saying he doesn't want to collect it now and can i just post it to him. I say no because of scammers i want you to be happy with it before buying etc. Any way he says a lot of things along the lines of "if its as described it'll be fine" "I'm happy to pay Paypal and add postage etc" all just really keen, nothing can go wrong but a bit forceful as in a don't be ridiculous kind of way.
I eventually agree to post but as my Paypal wasn't set up properly coming up with an error message he agrees to send the money to my dp's Paypal account. It goes through fine.
A week later now my DP gets an email saying the guy is not happy, saying its not as described as there are scratches on the back, and he wants £50 back!
PayPal has now placed on hold £130 including the p&p from my DP's account.
My ebay shows no complaint coming up. I checked this guys feedback and although he has 100% feedback, he has 3 recently that says he is a fraudster/ scammer who has done the same to them with their iPads too 
So how can i stop this guy getting an extra £50 back as this is clearly what he does to get more money off and get them cheaper? How can i prove it was as described?
Can i phone Paypal and explain my iPad was as described and tell them to look at his feedback as he has clearly done this before?
As Paypal have already put my partners money on hold are they just going to give him the money anyway?
If i just ask the guy to return my iPad whats to stop him saying he posted it and claiming the whole money back but still keeping my iPad? I'm so pissed off he's done this, sorry for waffling but what do you suggest i do? I dont want to lose £50.
