In fairness, it may have not been that actual cashiers fault, it could have been left there by someone else working in the branch. Ask the bank for a copy of their complaints policy, put a complaint in writing to the branch manager firstly, advising him that unless a suitable response is received within a number of days, you will escalate to the Financial Services Ombudsman and the Data Protection Commissioner. If you can find out the area managers name, include him in the letter
It would seem that this cashier is at fault as my father had been in branch and this Cashier was giving my dad some financial advice at the time and looking into something for him so it does look like she put up the note to remind herself, god only knows how long it had been there for..
My father while he is upset and fuming does not want the cashier to get into trouble or lose her job, he says thats worse to have that on his head. I want him to make a complaint to the Data protection but I think my father will be in two minds as he does not want this person to suffer..
If this were my bank account etc then I would be making the compaint immediately. He says there is no way to undo what has been done and he is right there but its so frustrating if he does not make a formal complaint, the banks should never ever leave private info lying about..
Maybe he will feel different about making the complaint later, I hope so..
