Terrible communication, No feedback and No service

I have been contacted by a consultant named Gogo, to make a payment. This after I called in and emailed Mixtelematics on the 1st of November informing Mixtelematics that my monthly debit order did not go off on the 1st as agreed. I was told that a double debit order will take effect on the 1st of December. However this was not the case. The amounts taken was not double and still left me with an arrears amount according to the system. This could result in my subscription being possibly suspended. All because of a sales consultant that wanted to sell me an upgrade on the 24th October. This matter has left me terribly stressed out and concerned.
There were two options proposed to me by Regional Manager Marius and he would have contacted me to confirm which option I would prefer. He never made contact again. I am still in the dark because I was never allowed the opportunity to choose one of the options I was offered and I am still having issues with the debit order amount. The fact that my subscription could be suspended and Mixtelematics affecting my credit rating/score due to a fault caused by your system is not fair. Due to the fact that I am still unsatisfied with the service and the financial implications that this matter has had on me and the personal inconvenience such as the time and energy I have had to put in to make sure my subscription is not suspended due to someone not doing there job or a system error. I will be making my way to Mixtelematics offices in Vorna Valley Midrand to address this matter in person next week I will appreciate if a manager or a member of senior management will avail themselves to address this matter.
