Cartrack Consultants Harrasing Clients.

I wrote a review on Cartrack accounts department telling that my account is in arrears. I've paid the R52 requested by die social department consultant, Mohammed. My account was now up to date according to the sms & watsapp massaging services. Now, they Calling again to say that my account is in arrears, and it's not even the new month of December. Whereby I pay the said R99 per month on the 2nd of every month. Please can someone tell me, how can I get rid of this pathetic ******* service from this company. Really this is so annoying. Yet my account is up to date.
