I opted for the Click and Buy account.
I had to update my credit card details for the account; stupidly tried to do it at work thinking I knew which password I had used but it ended up that I couldn't remember it, so I contacted them for a password reset to my registered e-mail address.... it took them 6 hours to send a simple password reset so that I could access my account.
Yes, it was my own fault, I fully accept that, but I did not expect it to take them that long to do something so simple. Makes me worried for the time ahead when they are actually charging me.... Fingers crossed that it was just a one-off. Oh, and I'm pretty sure at the time that I could not find a telephone number to contact them on (e-mail correspondence only ><).
