Incorrect ABSA Business Account Assignment

I signed up for the Business Essential Lite package in Mid August 2017 cost is R99 pm. The confirmation letter was sent by Sanele Mkhize (Cresta Branch). I deposited R300 into the account with 30 days of opening the account. I started receiving notifications the following month advising me that I'm in excess, to date I'm in excess of R450. Last week, on the 8th November I went to Cresta to close the account, due to these charges. I was told that I'm actually on Business Essential package thats R199pm, later on that day I forwarded the confirmation to the same Banker Sanele Mkhize, and asked him what is the way foward. He didn't respond to my email', I went back on the 10th and 14th where his colleague said he had changed the account to Lite Sanele will sign upon returning from lunch and would call me to confirm this and reverse the charges. I'm still waiting, no communication, I'm not going back for the 4th time!!
