DOUBLE DEBIT EVERY MONTH

I took up a personal loan with Nedbank in June 2015. Since then my account has been double debited every single month. In July I went into the branch at Carlswald to report this incident. I was advised that the matter would be seen to. Once again this has taken place, these are not small amounts of money that is being debited off of my account and quite frankly I am tired of this. I want this issue to be rectified immediately because the call centre agents are not capable of assisting me and I do not see the need for me to be on the phone constantly for Nedbanks errors. This is pathetic service and I want to be compensated for the inconvenience. Further to that the call agent Zandile Sithole (NB 205602) saw the need to tell me what I should and shouldnt say and how I should answer questions, I am already and irate client. I do not need to be annoyed any further! Nedbank is this what you think is acceptable!
