Stay away from paypal

This group I have heard some ***** stuff about and never took it serious because it look legitimate and official - trustworthy group. This group allowed 2 3rd party groups to take money off my personal bank card linked to them. I never allocated money to paypal to do this, so just jack my card right? If I was going to pay for something I would put my actual account details on that site. This is very ***** and ********* practice!
