fromWesbank to Worsebank

My account balance with Wesbank was less than R400.00 on the 15/02/2018, they debited my account with the full instalment amount of R2700.00 instead of the balance. On the 16/02/2018 I logged a call asking for the refund I was informed that I will received my refund between 24-48hrs. The 48hrs lapsed and I still didn't receive my money. On the 21/02/2018 I called to follow-up I spoke the consultant by name of Promise wjho went on to promise me that within 30mins the money will be in my account and this did not happen. On the 22/02/2018 I called to follow up on Promise's promise and I got the lady by the name of Sharon who assured me that her Team Leader was walking to refund section as we were speaking the money will come through before the end of the day. And today (23/02/2018) I have not received my money. I made a follow up and talked to the lady by the name of Shantel who also told me that her Team leader was going to the refund section to sort it out again, and I wonder how far this section is for it to take to day to reach. I requested to speak to the Team Leader, Mr Naidoo, what a rude man. He told be they will sort it and Sharon was not refereeing to him and they work differently as team leaders. It seem Wesbank just turned into my Worsebank.
