Cancellation issues

After how many calls must we go trough So on the 4/11/2022 i wrote a reveiw abou MIX Telematics. The lady told me the unit will be cancelled and i will be held liable for the payments that was not made and the removal of the device. Fine but I didn’t want to pay at first because i was not under CONTRACT with them. And secondly they just have my name and number. They also proceeded and told me they will call me in the week of the 7/11/2022 that phone call im still waiting for!!!!!! On the 15/11/2022 I called them just over 30min on the phone with them from the one agent to the other. That bring my time on the phone with matrix just over 4 hours. And now they telling me i must pay up to get the unit removed. A UNIT I DIDN’T asked for and a unit the must have removed in 2021 already. Matrix im highly disgusted in you and will never in my live recommend you. Finaly on the 15/11/2022 im getting my unit removed since struggling from March 2022. And the agent that helped me told me she can’t understand what was the problem because the unit was cancelled. So now i ask you few months has passed many phonecalls i had to pay for and now the Removal… Will i get my money back as I didn’t even signed a contract? Looking forward to your reply.
