STD Bank Business Non-existence

I requested feedback from STD Bank Business on a deduction of R552.19 deducted on the 7 Jul and previous months. Could not place the reason for the deduction. I called the number on the app and was informed my Buss acc manager contact details are on the app. After verification, it was confirmed not correct. I was given the e-mail address of my buss acc manager Massi Mpololo, who till today not feedback to me. I logged a call and was given a incident number and advised they will get back to me 28 Jul . Today is the 4/08 and still no feedback. This month I notice the deduction does not reflect. But then he comes and threaten me with closing my account because I must now declare my source of revenue. If it was not for the burden of moving the business account, I would go to Capitec Buss, where I can walk in and sort out my issues, face to face. I know who I am dealing with, and get customer service.
