Charged R1471.62 in banking charges instead of R169 for my premium cheque account

I am a premuim cheque acvount holder and was shocked to see my banking charges for Dec 2017. I was charged R1472.62 in banking charges instead of the R169 monthly charge I signed for. I got charged R858 just for internet banking and the free online banking is part of the premium cheque account package. This is daylight ******ry. i logged a complaint with absa and was told the query would be investigated and the process will take up to 5 working days. Can this be experdited as I cannot afford to be a client of absa bank with such high rediculoud charges. I chose to open a cheque account to minimise the banking charges that were on my savings account and it seems I have gone from bad to worse. The next step will probably leave absa altogether. My reference number is **********
