Worst tracking device company EVER!

Early last year I took up a tracking device with Matrix as someone highly recommended it, the tracking people came to my home and installed the device. I then received a call on the same day to activate the device and was informed of the monthly premium of R185.00 , but that was not the case as they started debiting more, called in to inquire and was informed that I was subscribed to some Road Assistance for R70 p.m which I did not agree on and was told that it will be cancelled but they continued to debit for it plus the premium and so I started reversing the debit orders and only paying the agreed premium of R185.00 .In July same year (2017) I decided to call the cancellations department to cancel the account because I was still being charged for what I did not agree to pay , spoke to Jade who told me that I am on a 3 year contract and needed to pay a cancellation fee. I told Jade that I was never informed by the consultant who activated the tracking device about a contract and did not accept such an agreement, she said that they would listen to the recording and revert back to me. That never happened, instead Mixtelematics sent me invoices/statements stating "BAD DEBTS RECOVERED" with R0.00 balances, which to my knowledge means that I do not owe them anything. Months later, 11/04/2018 to be exact, i received an sms stating that I have been handed over to SSDA Attorneys and need to pay.

I demand to know how I am handed over when I did not receive the recording proving that I accepted the 3 year contract and have not heard anything whatsoever from Matrix since my last phone call made to them in July 2017???
