Standard Bank Vehicle finance incompetence

Standard Bank Vehicle Finance (Your case number: ***7). My debit order did not go off as per usual. I was informed that it was due to the interest rate change. I phoned and they said they will rerun the debit order. Which they did, but then the debit order went off again the next day. I was then to mail proof that the debit order went off which I did, 4 or 5 times but the person assisted me only received the mail with the attachment being stripped of. I then, giving up hope, said I will go into a branch. The one where I used to go is no longer there. I phoned again this morning -- been 4/5 days since it was taken of my account, but it still not reflects on Standard Bank side. I have wasted a day and half to sort out their mistake. And it is still not sorted. I have to wait till it reflects on their systems and then I have to request for a reversal -- so basically have to do their jobs for them. I cannot understand how they can be in banking at all. I have to wait till this is sorted before I can get a settlement amount. I deeply regret ever doing business with them. A mistake I will never repeat.
