I purchased an item recently which was described as immaculate and as new.On opening the packaging i immediately noticed a very obvious repair and contacted the seller at once for his comment,to which he went on the defencive and implied i was a liar.Short version,i filed a dispute with pp and escalated to a claim for a refund.The seller maintained an air of innocence and dug in over this.PP at this point requested that i gather supporting evidence from a neutral third party at my cost and send this to them.I complied,they transferred the auction cost plus p+p, result and end of story...well not quite.The seller is spitting nails and demanding i return the item at once....no issues at all with this except he is expecting me to arrange the shipping and pay for it - aye right
The bad news for him that he doesn't know yet is he's now in the firing line to cover my expenses in terms of collecting evidence,faxes to forward it all etc etc etc.PP have informed me they will assist and support me in securing this from the seller.The point being it would have been in his financial interest to co-operate from day one rather than call my integrity into question and attempt to draw me into a bun fight.
I accept you have sent your item in good faith however as paypal don't know this they will request your buyer gets supporting evidence.....at this point you may be Donald Ducked to coin a phrase and pp will refund him at your expense plus you will have to pick up the tab to have it refunded (at which point the cpu gets put to death if it wasn't already and you get neg feedback into the bargain).
You may be in a no win situation here so it's a case of damage limitation.
