I am used to US credit cards and moved to Germany a few years ago.

In Germany credit card chargebacks are very cumbersome. I had 3 banks' customer service tell me at first that it isn't possible (like they had no process for it or the agent never did that or is too lazy) and then the next agent said it works but has huge-list-of-drawbacks-fill-9001-forms-and-waste-days effort.
