Poor Customer Service coupled with Serious levels of Incompetence - Standard Bank in No.3 Simonds Street

I recently deposited my money on a Standard bank savings account. I was first debited R4000. I went inside the bank to enquire. I was told it is for an outstanding cheque account. I then submitted a settlement letter showing that I paid off the debt in January 2017.

After 3 days I got back my refund. Two days later, it was the same story. an amount of R3200 had been debited and I called the collections department, after 3 days, I was refunded. On Saturday, 7 October 2017, same thing happened. an amount of R1900 was debited. I was livid. I went to the branch in the Glen Mall. I was told they couldn't assist me. I must call on Monday. I called them on Monday. they promised to refund me my money by wednesday. 5 days later I'm still waiting for my refund. I've dealt with Tiisetso Mohali; Eunice Mlangeni and Lebogang. Service is so pathetic.
