Skype.
For some reason or other ("security") they have blocked my account so I can't use it.
The account unblocking process is ridiculous. Questions range from the reasonable "what credit card did you last use to purchase credit?" & "list 3 contacts" to the ridiculous "what month and year did you first use skype?" and what email address did you use when you
originally signed up?"

So far they are refusing to unblock my account and are suggesting that I sign up again.........I'm thinking so that they can simply block my access and purchased credit again?!
