Useless Private Banker

It first started when FNB changed my private banker. I had a simple request when I had to change my home address on my account to co-ordinate with my application to buy a new car. I mailed my private banker Ashvick Sewkarran with my new rental agreement contract. 2 weeks later he only got back to me saying that it is not good enough to change my address,and asking for something else. Where in less that 4 hours I gave that same contract to Wesbank [which is part of FNB] and they changed my address and gave me finance on that address for the new car.No problem at all. So I mailed a vodacom invoice,hoping this will work. 7 days later he only got back to me saying it will not work because it is on word format. Well I can not help it is this is what I get from vodacom. But only a week later you can tell me this!!! So I decided to call him,first call he was busy on the line and a message was taken to call me back.1 hour later the Second call was transferred to his phone and no answer. Third call another hour later at last I get hold of him asking if he got my message and he confirmed yes. But when asking why he does not call back he had no answer. After the conversation I decided to send him an invoice of my wesbank statement and a payslip with address on it and again 8 days later I got an email back that this is also not good enough. I mean after 4 weeks you cant get back to me swiftly and explain exactly what you need to change a simple address. So I work abroad and my previous tour over I mailed my previous banker saying that I will be using my FNB card in that country. She said no problem it is set up for using with out any problem. This time I did exactly the same and he said that other people will call me to confirm ect. But guess what,It was another 9 days after I mailed and I was already abroad. So I decided to tell him that I cant have this delay response from a banker,where it is suppose to be easier and faster solutions to everyday requests,I would like to have an email address of the manager to request a new banker. He ignored what I asked for and mail after mail every day he until this day has not responded. What type of service is this from a private banker that is so useless and does not have the decency to reply or call you back,and take weeks to get nothing done.
