Unexplained terms and conditions (Hidden T&C's)

I cancelled my Matrix subscription around January this year (2019) due to the fact that I changed my vehicle and I did not need the tracker in my new car anymore. I sold the vehicle in question in 31 December 2018.

Matrix are, to this day, still debiting my bank account for this subscription. I have attempted to cancel this subscription telephonically on several occasions without success. Matrix's modus operandi is as follows:

1) After phoning the customer care line, Tracker provides me with verbal confirmation that my subscription has been cancelled. 2) The requested e-mail confirming cancellation is never sent to me. 3) On the 1st of each month, my bank account is debited again.

The concerning part is that where you are purchasing the tracker , these terms and conditions that you need to subscribe for a certain period are hidden to us clients.

I feel it is unfair and ******* in my opinion.

I would like get tracker to get back to me on this matter as soon as possible with possible solutions on how to : 1. Stop the subscription 2.Get refund of my monies paid from February 2019 up to date. 3. Never ever ever offer me one of their services either by telephones or ads. Im disgusted and financially strained by their horrible services.
