NOBODY able to assist & bad attitude

I'm terribly disgusted with the service I have received from FNB over the last 2 weeks. I bank with the institution myself and now need to open an Estate Account for the lawyers to process my late mother's Estate. However, after spending over an hour in the queue at the President Square branch and being directed by an extremely helpful lady, the teller sat back in his chair and refused to help me as my proof of residence was not a utility bill. ALL my records are on their system. But there was just NO interest in assisting in ANYWAY. Then, I tried to contact the call center in order to ensure that I have ALL the correct documentation and I visit the correct branch/follow the correct procedure only to be transferred by the operator to the Estate Department , without evening listening to the full query, who were INCREDIBLY RUDE and unhelpful. The lady could not even point me in the correct direction, had no idea what I was talking about and could blatantly not transfer me. She didn't even listen to my query. I am SEETHING. If this is the service one gets with dealing with an unpleasant necessity I may just have to move my accounts.
