18 months since notification of cancellation

In February 2023, I formally notified Cartrack of the sale of my bakkie and provided them with the pertinent details of the new owner, including their phone number and ID number. Despite this, it has come to my attention that Cartrack continues to attempt to deduct funds from my account. Unfortunately, there hasn't been any further communication from Cartrack about the resolution of this matter since my notification of cancellation. It appears that there may be a deliberate delay in the cancellation of accounts, potentially aimed at maximizing financial gain.
