Review and due diligence not done - Poor customer service

CLI*** ***

Ombudsman please I need your intervention with the below

My car that I used tracker for was a trade in last year in Oct, and I called tracker to cancel my contract with them.

YTD I get calls they claim that I am outstanding payments, payments on what exactly on a car that I no longer use.

If they had done their due diligence, a review on my account they should have picked up that I no longer use their services as I have called and cancelled

30 Sep 2024, I received an sms indicating that they have reinstated my account and the debit orders also, for what if I may ask

I no longer drive the Hyundai

In the month of September they again debited my account and I returned it

Today 18Oct 2024, I receive a call that my acc is being handed and I have outstanding payments
