Paypal unfair ruling.

I am writing this as a warning forSELLERS as they do not seem to have any proper backing and are often let down by red tape. I sold a pair of boots and the payer paid with paypal. I then made the mistake of sending them parcel post WITH proof of posting and areturn address.The buyer then claimed she never recieved them (they have not arrived back to me) and even when i provided proof of postage paypal still refunded the payment to her telling me proof of posting was not enough. Her word was obviously morebelievable than my piece of paper.Watch out how you post items as youcan loose out with paypal, it's safer for the buyer than the seller.
