Charged on Terminated Accounts

That's the worst service I ever experienced in my life and I will never stop knocking on the doors for help till I get justice. I feel like climbing the mountain and tell the whole world how ******* Mix telematics is. I called and send an email to terminate my two accounts I had with them and that was done only on one vehicle only only to find that the other one was still running, me not being aware. They still continued to debit my bank account with the full amount for two cars though they claimed and confirmed that the one account has stopped. I call customer care line and they said the contract for one car was not 24 months old yet so I have to pay a penalty fee and the account will be closed. I paid R2270 upfront but still the monthly payment was taken from my account. Yesterday for peace sake they said I owe R413. 68 which I paid again but when I called for confirmation of payment still I am told that I was supposed to have paid R600 according to their books. Look all these payments that I pay its because they BLACLISTED ME THAT I OWE THEM. I am tired and I will never give up till they are exposed of what they do to poor South Africans. Matrix please get your house in order and customers should get value for their money. I need my name to be cleared for the past two months that I lost points on my credit profile and my two settlement letters. I can't suffer for your Mistakes.
