Ignoring requests for a chargeback due to double charge!

It is a pity that I have to come to these platform to deal with queries after spending R100 on airtime and multiple branch visits. On the 17/18 I went to sandridge branch to report a double charge and requested a charge back, a guy called Khathutshelo helped me with filling in the forms but one month later the call center has no record of my disputes. The result has been one of my transactional accounts sitting at a big negative and this bank continues to charge overdraft fees as if it is my fault. I no longer have the time nor resources to stay on phone calls for 20+ minutes and I need my query resolved. This bank is seemingly going down the drain and I hope to see it collapse in my lifetime.
