Worst mistake of my life: Agreeing to be upgraded to wealth

I have been a happy customer of FNB for some years now. A month ago or so I received a call saying that I qualify to be upgraded to wealth. I was not keen at first because I was happy with the service I was getting from my banker (Mosemane Moloto). I actually asked if I can keep him as my banker after the upgrade and I was told NO and assured that with wealth even the service will be upgraded. I then agreed to be upgraded. At the time I was considering buying a car and a house and I was not sure whether I must complete these transactions with Mosemane or not. When I told the person who was recruiting me she said if I do those transactions as a wealth client I will get better rates and this is one of the things that persuaded me to upgrade. After I agreed I was told that my new banker will call me in 2days to start the process of the car and the house. 1st disappointment - I was not phoned until I decided to call. 2nd disappointment - I dealt with 2 bankers that were not helpful and not interested in helping me e.g. if you don't call you don't get any feedback, everytime you call there is either a missing document or something but they don't communicate, I then asked to be downgraded back to Mosemane but Thandokuhle (one of the 2 bankers) asked me to stay and she promised to change. Indeed she changed and was communicating regularly. A week later she resigned and the nightmare continued. I am told even the 2nd banker has resigned. A new banker has been appointed, worst banker ever compared to all the bankers I have had with FNB. 1st I asked him for feedback about my 2 applications and he had no clue what I was talking about (of which for me it was strange given the fact that I have changed bankers in the past seamlessly), I then briefed him and gave him the document that was outstanding for the process to be completed. When I made a follow up, he told me that I must send him all the documents needed for the application. I refused because to me it sounded like he wants to start the process afresh and I don't understand why. Even if he was not briefed about me the least that he could do was to check homeloans and wesbank instead of wanting to reinvent the wheel. 2nd, I sent him an urgent email about a debit order that I don't know in my account. He did not reply or call to try and help, which made me angry (It means people can ***** money from my account and my banker will not treat it as urgent). I then phoned him to check about the debit order, he told me that he doesn't deal with such queries I must call the wealth suite and ask them to help. He further explained that he doesn't deal with transactional queries in future I must call the suite. I asked him what his role is, he said he will help with things like homeloans, car finance. The way I understood him it looks like he doesn't deal with day to day banking which is a problem for me because Mosemane was a one stop place for me. It looks like now I must call a call centre for a lot of things and I don't have a particular person who helps with my banking. Back to the debit order, he said he was going to call me back the same day at 16h00 to see how he can help. He did not call. The following day I phoned him and he said he lodged a query on my behalf with the relevant people. I haven't heard from him since. I then remembered that I once had a situation like this and Mosemane taught me how to reverse a debit order online. I asked around to refresh my memory and cancel the debit order. My worry about this is not the amount (the debit order was R99) is how things are dealt with. For the 1st time since I started banking with FNB I am feeling vulnerable. I don't feel my money is safe at all. I am actually very worried. Another worrying thing is for the 1st time I was charged for using a slow lounge at airport and I was told is because I have been downgraded on ebucks, which was strange for me. Anyway I have soo many things I am unhappy about that happened in the past month and I am going to stop here because already this is long.
