Card was fine until 4am In serbia a few days ago they suddenly blocked my card as soon as I was supposed to pay for my cab...So embarrassing and inconvenient.
Religiously. They blocked my card for days while I was in Europe putting me in a most uncomfortable position. Then in the US, they blocked a US$1,500+ bill. I could only pay US$50 at a time, so I had to insert my card 30 times at the cashier and got charged a fee each time.
