Have had an account with them for 2 years. They started blocking my transactions because they look "suspicious". Last time around, the same transaction was made by several friends from their own accounts at different banks (we were all buying tickets to the same event from the same website) and guess what - only my transaction got rejected twice and I had to spend 15min on a customer call only to be able to spend £100 from my own account.. Have asked the customer service and they say there is no other way around this, not even a text confirmation instead of me calling them every single time. I'll give it 2 more strikes before switching bank.
