TRACKER TAKING MONEY AFTER CANCELLATION

On 30th of May I phoned Tracker in order to cancel my current policy, I was requested to forward an email, which I did on the 30th of May 2023. On the 31st of May I received an email that the policy was cancelled. In August I have noted that the payment was still being deducted from my account, when enquiring about this they said it was an additional product that was cancelled. However, the policy number was on the heading, I stated that I have no intention of renewing the policy and that my intention was clearly to have it cancelled. I have no idea of what additional product they are talking about, I only have one policy document and one reference number. And if they have cancelled and additional product, why is the payment still the same?? When my wife phoned them today (7 September), they were unwilling to phone me in order to assist. I have to phone them, but I am paying for a service. She asked for the financial institution registration, which they could not provide, asked for company registration, which they could not provide, asked for a call reference, which they could not provide, the only thing she could get out of them was the name of the lady she spoke to, Andisiwe. This Business is providing a lot of unclear information, not even sure if this is a legal business. They have been *****ing my money by deducting payments after cancellation of my policy. When asked to speak with a manager, my wife was refused, when asked to speak to a director, my wife was refused. When she explained that it is difficult for me to phone while at work and to hold the line and requested them to quickly call me in order to obtain permission that they can speak to her, they refused. But they are quick to have you take their policy. Should a car get ******, and they can't make calls, how on earth are they going to update clients on the where-abouts of their ****** vehicles.....
