Terrible accounts department

I missed my debit order on 27/012/2021. I then called Cartrack to make an arrangement. The arrangement was that Cartrack double debit me on 22/01/2022 The agreed amount was R178 (Due to the missed debit order) and an amount for R169 (the correct monthly payment). On the 22/01/2022 they debited R178. Then on the 27/01 they debited another R178. I did not query this as I had missed the debit on 27/12/2021 and I felt bad, I left it as is. Cartrack then debited AGAIN an amount of R169. I call them to find out what is going on and they apologize. I told them that I am reversing the debit order for the amount of R169. I reversed the debit order, the next day I get a SMS saying that I am in arrears, I call them and they say I am not. I get an email saying I am in arrears, I call them and they say no I am not. The next thing I get a debi check mandate to approve for an amount of R180!!! I call them AGAIN to ask why is the amount R180 and I get told that the previous consultant should have explained. I ask explained what, I get told that consultant will call me. I HAVE HEARD NOTHING!!!
