Barclaycard Takes Over £2000 From Barclays Bank Customer's Account

Barclaycard shows no mercy if one of its customers goes into arrears on its credit card account. If the unfortunate person happens to have a Barclays bank account Barclaycard just helps itself and takes the money out of the account, leaving the helpless account holder unable to pay the bills. The unfortunate victim was unaware his account was even in suspension. Nobody had bothered to tell him.

And you have given the first of the friends advice that will help others avoid this sort of rip off behaviour. (They'll quote small print)
Well done. I'll avoid that mob.
