Unaccounted for Charges and Lack of Service

I am endlessly disappointed by the lack of service and support from Absa regarding a complaint that I have lodged with them 3 times in the past month with very little to no follow through or resolve from their side. Since the 1st of March I had suddenly been charged more than R1000 worth of charges/fees by Absa with no due notice or explanation provided to me. This happened again on the 1st of April with the fees/charges amounting to over R600 and causing one of my debit orders to reverse, which I now have to pay for manually. I have emailed and I have called on numerous occasions over the past month to try get some explanation for these charges/fees to no avail. I have also been told that the branch manager is the responsible contact person and has been made aware of my complaint, however I have still not received any due feedback to date. This has been ongoing, frustrating and tiring on my end as a client of more than 10 years. If I cannot have this resolved I will be forced to close my accounts and take what I have elsewhere. I cannot keep on querying the same issue with no feedback or resolve indefinitely, nor can I accept such steep charges to be app**** to my personal account on ongoing basis either. This is my last straw.
