I used their online chat facility, was told I couldn't do what I wanted, but as the website allowed me to do it, I thought I'd chance my arm and went ahead anyway - only to be send a very rude email pointing out that I had been 'told' I couldn't do what I wanted. When I pointed out they should change their website so that customers wouldn't be able to do what I did, I got a very curt response. I am still waiting for my card to be reimbursed. I know I was chancing my arm, but I didn't expect to be written to like a naughty child! I won't be using their services again.
