I'm in the USA and I much prefer to use my personal Amex card whenever I can because Amex has always had excellent customer service. My cards have been used fraudulently a few times over the years and I've always gotten a call from a human about it explaining everything and the next morning FedEx delivers new cards to me. When ever I've called them, they handle my issues very well. I don't think I've ever had a bad experience with Amex.
Same here. Also got the premium rental car insurance from them, and ended up breaking the tail light on the rental while in France. I had to just to call them a file a short form, and then they took care of everything else.
