I only did one attempt at a credit card chargeback in the past 10 years, and Citi denied it. So I won’t use a citibank credit card again, and warn you too. It was only about $100 and with priceline.
A few months ago however I asked PayPal to refund an autobill I had already cancelled, and it was a really quick process that took 30 seconds online. This was for about $60.
The best credit cards these days are Chase, Amex, and Barclay, in that order. Citi used to be a close second but they just don’t have the big bonuses the other leaders do.
