Gana lose another customer

I am self employed and have 4 business accounts and my personal accounts with FNB. I have been contacted on a regular basis to be unsold on products I cannot have and do not want because I am self employed. I have with every single called asked them to remove me from their lists and I will contact them should I be interested in a product. After a few calls I started asking for the advisor to get a team manager to call me so that I can sort this out. To date I am still waiting on someone to call me with regards to this. This evening was no different, again I get a call to try sell me something I cant buy (due to being self employed). I could hear that the advisor is in the call centre and asked to speak to the team manager because I am very close to closing all my accounts because they cannot follow instructions. The advisor does not even know his alphanumeric alphabet to spell his name, which I will with hold for legal purposes. Was advised they will listen to the call and then a team manager will call me. NOT good Enough. Gave them 5min to get a team manager to call me back and listen to the call on their own time. Which has now passed. Maybe I should close ALL MY BANK ACCOUNT with FNB. Very upset!
