Poor customer service

Good afternoon In October 2023 Mix Telematix installed a tracker in my car. They told me that they will debit the first installment of R189 on the first of November and that after that first installment the tracker will be activated. Nothing happened on 01 November 2023. Nothing happened the whole of November. The tracker was never activated. I never used their tracker. I called them to no avail. I concluded that they have dumped me. I then moved on and joined another company. On 01 December 2023 they debited my account the amount of R371 - 91 and on 22 December 2023 an amount of R189.01 was debited.

I disputed both amounts and reversed them through the app. I further wrote them an email an requested them to explain why they dumped me without explanation. In my email I also requested them to give me proof that i agreed to the amounts debited as well as the dates on which they are debiting. To date I received no response from them concerning above queries. What they are doing every month is to send me invoices reminding me to pay. At the moment the amount according to the latest invoice is more than R900. The reminders are done monthly but the emails that I wrote in January 2024 and December 2023 have not yet been responded to. All I am asking is for them to explain or stop sending me invoices.
