Internet purchases

I use paypal but when i had a problem Paypal sucked. I called my credit card co and they checked into it and they put a stop payment with paypal. Paypal wasnt happy about it and tried to charge me for their services. Concacted my credit card co and they took care of it with no charges on my part. That was 2 years ago and i still use paypal. The credit card co was mastercard if makes any difference or not.
