How secure is PayPal and their transactions? I'm not a registered user of PayPal but somehow over the weekend someone got a hold of my credit card number and had a field day with it paying for unknown items using PayPal. All the charges were in 3 digits always with an even $ amount. I contacted PayPal and they gave me the persons e-mail but somehow I don't think he'll reply to my messages. They are investigating and will get back to me in 3 - 5 days. The bank in 10 days.
