Standard bank' bad and unprofessionalism dealings with me

My wife and I opened a business account at the Florida branch and we were allocated a business banker. All was well. We asked for help to find our business, to grow it. Standard bank didn't want to help us. Our dedicated banker was them moved to Westgate shopping centre. Our problems started then when we went to the branch and no one was prepared to help us. We were told to follow our banker and so we decided that they must close our account and they refused. Our account was clear since we did not have any loan or overdraft facility. After some time we started getting calls from the bank saying we owe money. I told them we do not owe them anything. We were threatened with legal action and by then they were demanding more than R6000-00 which I refused to pay. For this, I will never associate myself with Standard bank not recommend them to anyone. I kept getting calls of demand when they did not hear my plea for help. At some stage, my uncle passed away and my cousin sent me money from the United Kingdom to help with the funeral and Standard bank intercepted the money. This created bad blood in the family because they thought I used the money for myself as I was not employed at the time. If Standard bank was the only bank, I will keep my money under my pillow. It will be safer there.
