Business Banking service is horrifying

I was liaising with my so-called business banker to change my business address. He told me to come to the branch with proof of address. I explained to him that the address was not in my name and I was working from home. I was told to come to the branch and a plan would be made. I get to the branch and he refers me to a consultant who hands me a form for my husband to fill in. I wasted my whole morning to get handed a form, which the banker could have emailed to me. when I called him to tell him what had happened as he had left the branch already, he said sorry and that it was not his department! Really? Don't you work for the bank? Surely procedures for changing an address would be something you, as a business banker should know and if you didn't don't you think that since the client is querying it, you should get the correct information? Now, I have to make another trip to the branch again with the completed form! FNB Personal banking is excellent, but business banking experience leaves a lot to be desired! Would definitely not recommend to any other business.
