Poor Service and lack of proper communication- Ignorance

Poor service and so much ignorance from Banker up to their Management. I have a car finance with Standard Bank and payments started not to reflect on the statement. I reported the this issue from February- calls and emails but no assistance. One banker even asked "why are you paying more, this is confusing the system, why don't you wait for a debit order" You have to call and get allocated to who ever is available, no direct number even when you have an ongoing concern, you then need to explain and forward all emails to who ever is allocated that day. I asked about financial charges that are far more that monthly payment (10k and above) and no solid answer from this bank. Standard Bank is really frustrating and cant wait to get another Bank to take over this car finance.
