Complaint about the Complains department

I have been trying to close my business bank account from abroad since February. I was asked to submit certified copies of various documents from abroad to which I said NO to as its going to cost a lot. I tried complaints department but after the initial email nothing happend. They cant verify me telephonically because my international number is not a SA number. I have complained on Hello Peter then and got a reponse from Standard Bank but after the initial emails nothing happend. I’ve sent follow up emails to no avail. So does the complaints department not have any teeth, do they not follow up in requests or something else? Just close my business account! You have several emails as support, you now have x2 Hello Peter complaints, but you just cant close the account!
