Bad customer service

I have been receiving appalling service from Standard Bank from receiving incorrect information to being transferred to incorrect departments. Your agents have no care for their customers. I went to Standard Bank Westgate twice and it's closed. I just want to close this account. I spoke to Bulelwa Nyhaba on the 24th and she said I should make a payment of R2277. 87 and she will close my account as I have explained that the closest standard bank to me is closed. She said I should email my proof and it will be done but to my surprise she is not responding to my emails. When I called in yesterday I am now told there is interest I now need to pay. Where is that coming from because after making a payment I received an sms saying my account is on a 0.0 balance. I am so frustrated with standard bank I no longer want anything to do with you. obviously you need to have alternative ways to assist customers since we are all facing a pandemic but that's not the case with Standard Bank.
