Poor customer care

Been trying to get my card debit order set up over the past 9 months as when I pay it’s rejected as wrong account details, I call in to resolve the issue and they have record of me on their system. I now get notice from a third party to say I’m handed over. I then call discovery and again they tell me sorry we don’t have any details for you on our system we can’t help you.

Guess the ombudsman is my next course of action
