if you want a second opinion from where i'm standing if it was sent with faults you knew about but didn't show these when advertising then its clear that you have misrepresented the product and so a partial refund was probably in order (the amount of course being at your discretion). personally from what i understand this would not be worth £50 but that is your decision.So i lose £50 on something either RM do or himself?
it couldnt have been much of a problem if he went and spent that £50?
Not being funny but i just lost £50 over nothing?..
alternatively, if the damage was caused by royal mail, if you sent this properly insured (e.g. special delivery) then it is the recipent's responsibility to raise a dispute with royal mail (and not the sender if i'm correct?) and seek compensation from them and not the sender.
bottom line is that now the best you can do is try and raise the point with your buyer and hope that you can reach an agreement to remedy this. obviously it would appear the buyer has some screwed up morals for taking this money from you but at the same time you should not have given him a refund so easily.
