Tracker not updating my account after they made an error on my account.

Sometime around June 2024 I purchased a vehicle and contacted Tracker to request for them to instal the unit on the new one. I was advised of an amount payable when moving a unit to another vehicle. I agreed on it however I requested the amount be split over 2 months and the agent agreed and arranged for it to go off over 2 months including the monthly premium of each month. A few days later I get notified by the bank of a failed debit order and upon checking, it was Tracker and they tried debiting the full amount which I didn’t make provisions for. I contacted Tracker and was advised that the consultant gave me incorrect information, the amount cannot be split. Then they advised they would investigate and see what they can do. Nobody ever came back to me. I phoned in and got transferred to Siyabulela Rabela who acknowledged the error and in good faith offered me a 50% discount of the once off fee. Thereafter I also started making payments trying to update my account. Then my account got handed over to Blake & Associates and those agents are the rudest. Only when I explain my situation they would understand. I also spoke to Sweleni from Blake who was the kindest, she understood and empathised with me as she could also see that this was not my fault. I’ve been asked numerously to mail my proofs of payments and also the email granting me the discount which I all did. Up till this day I am still handed over and every single time I’m told about the finance department that must update and consolidate my account as I have been paying. So far I have had no joy getting correspondence from Tracker but I get calls daily from these lawyers and they keep pestering me. Tracker is most certainly the worst. I don’t know what else to do by now.
