paypal took £750 from me because 2x buyers complained about their laptops. One took his apart and couldn't get it to work afterwards the other decided he preferred a brand new on instead after using mine for 3 weeks.
I lost the £750.00 one didn't return the laptop and the other buyer returned a ruined laptop in bits.
Since then paypal have frozen my account and demanded a further £150 they have frozen my g'friends and Father's paypal accounts although they have different addresses and are nothing to do with my ebay transactions.
Paypal are lying cheating thieves. Always use recorded delivery, always note serial numbers or mark items with ultra violet pen and never accept it for purchases over £50 or what ever you can afford to lose.
Once they have your credit card details its impossible to stop paypal removing any amount of money they choose from your bank account. Even your bank cannot stop the card transactions. Read the small print
