I hate paypal so much, I'll never use them again, despite the inconvenience. There have been occassions where I have not received an item that I have bought, and they have dealt with the seller and come back and said they can't reimburse me because the seller doesn't have enough funds in their paypal account. This has happened more than once.
Then, a couple of weeks ago, I sold something for about 20 pounds and the buyer - who was new - claimed that he had not recieved it. He told paypal that I had 'conned' him, and paypal took the money from me without warning. There was nothing in my paypal account, so that put it 20 something pounds in the red, and the account has been suspended until it is paid. So when someone else doesn't receive something, they get their money back even if there's no money in the paypal account! I was so furious with them I sent them a very nasty email telling them, in a lot of four letter words, exactly how I felt about their company. As I have no intention of paying this money to paypal, I can't use my account again, which means that buyers are less likey to buy from me. But I'm a student and I can't afford to give my stuff away. Oooh, I hate paypal!!! I've had issues with them before but just gritted my teeth and lived with it, but never again!
