The bank that just can't get it right...

I can't use my credit card - the paypoint accepts pin, but transaction is not going through. I suspect the previous private banker cancelled the wrong card, however the pin is accepted.

Lucia who I've spoken to was extremely unhelpful, and arrogant.

Consider adding to your validation process questions instead of bank cards, as it's difficult and putting customers in danger whilst they're driving to enter card numbers and pins.
