Dont worry E bay or should I say Paypal always support the seller, I bought an electrical item last year it cost £239 , when it arrived it was not the item advertised also it was faulty and kept cutting out. I e- mailed the seller who admitted it wasnt the actual item he advertised and was in fact a much cheaper inferior version, as per his instructions I returned it.He said he would refund me on receipt.
He then e mailed me saying I had returned the item in a damaged state..he included pictures supposedly showing the damage, these were of a of a completly different model to the one I had returned!!!
He refused to refund my money and it went to dispute . Despite all the evidence I had of his admissions and his illegal advertising Paypal found in his favour. I was disgusted I had made over 1000 transactions on ebay with 100% positive feedback. Needless to say I spoke to trading standards about him and he no longer trades on ebay............well not in the same name.
If you know they are pulling a scam on you refuse to back down ! Good luck
