Double deductions from African bank - absolutely pathetic service, query still not resolved and it is 12 days later

Here we go again: Incompetence of the staff at African Bank is astounding to say the least. On 19 April, African bank charged me for transactions. The exact same deductions to the value of R822.25 was repeated in my account. I called the bank on 20 April and spoke to a customer service person (Ria). While she was logging in the compliant the call cut off. As any good business would do I expected them to call me back, but they never did. I called in again the following day and requested to speak to Ria as she knew my issue which took me a long time to explain. The service person sent an email to Ria to call me back but she never did. I then called in on Friday 22 April to lodge in the same complaint. I received a reference number indicating that the complaint would be sorted out in 24-48 hours. On 25 April, Lefty from African bank called me to discuss my query. Unfortunately, due to the "wonderful" system that African bank works with, he was unable to authenticate me and indicated that he would call me at 3:30, a time that I had given. Unfortunately, my job is such that sometimes when you are in a meeting, the meeting goes beyond the expected end time. Lefty called once, he could not get a hold of me. I then received an sms to say "your request **** could not be met due to unable to reach customer". Hello, just one call???? I immediately called customer service back who traced lefty and left a message for him to call him back, which never happened. I then received the following message" thank you for your query for your uncleared funds ...". Where the hell did I query "uncleared funds". I queried "double deductions/charges". On 29 April I received a message saying that my query was resolved, but there was no change!!!. the money is still not reflecting in my account. I then called in today, at 15:19 and spoke to Busisiwe Masilela, absolutely unhelpful person, who had not customer service skills at all. Once again she could not authenticate me, and the "stupid" questions that they ask to authenticate you are just so ridiculous - they expect you to remember what information you completed 10 years ago, really. For example, one of the questions is: "how do you receive your statement?. But African bank never sends you a statement because you get it off the app or online. She has no patience at all and has NO SKILLS to work with irate customers who have been put into this position because of the incompetence of African BANK!!!! She then took down my cell number (note the time: 15:19) indicating that the team leader (Gugu Wala) will call me back as she is on another call. It is now 17:15 (2 hours later) and still no call from GUGU. So if the team leader cannot call a customer back and thinks so "lowly" of AFRICAN BANK customers, how then do you expect the employees she supervises to show compassion and assist clients? Really, African Bank you are bringing down the name of our continent. This is not the first time, you have "******", yes "******" money from my account and I had to jump through hoops to get it back!
