Debit Order

I had Car Track installed on my Vehichle on the 4/09/2017 through Audi. The debit order was suppose to go out on the 1st of each month. On the 2 October the Amoumt of R109 went out with no problems. On the 1 November I Was Debited 3 times ( 3 x R109) this month 2 December 2017 one debit went out (R109) and then again another today 8 December 2017. (R109). I even contacted the accounts Department and explained to them my concern and was asked to forward my bank statement highlighting the 3 debits. Which I did, so they could investigate. its a new month and I am still having issues. Makes me wonder if they can really keep track of my car as they definitely cant keep track of their customer payments.
