I find the deposit cost of 4% a bit high. What angered me was that I agreed to €3.75 cost for extended limits. The uploads took forever and at the end I was informed they were insufficient. Fine, but what more did you need? When I sent an inquiry as to what went wrong, I received no answer. I still intend to use the card. Maybe one day we will figure out what went wrong with the extended limits I paid for.
