It's happened to me a couple of times in the past, like maybe 3-4 years ago.
Not had this happen for years now, also I wouldn't complaint too much about it as it's there for your protection and once you go through the checks which take a couple a minutes you can purchase whatever you want and use that site and service again without worry of it happening again.
It's only happened while purchasing online, never while in a shop or restaurant.
The funny thing is some sites completely bypass this protection.
