Jalexa, agree wholeheartedly with you about continuous payment authorities; the only real problem I've had (fortunately) in 35 years of using a credit card was with a recurring payment for a monthly subscription - took nearly 9 months to sort out and the card supplier was extremely unhelpful- cancelling the card didn't stop the wrongful charges.

There definitely needs to be a mechanism to stop these with the card supplier WHATEVER the merchant says. If they have a rightful debt then there are ways of recovering the debt.

I also agree that there needs to be a control on credit card limits - I have had many unasked for increases on both my cards without EVER approaching anywhere near the previous card limit.
