Trackers utter lack of Administration caused me to be handed over!

I want to address the error made by the Administration department of the Tracker company. In 2013, we had a contract with Tracker. The contract expired. In October 2024, we app**** for a Tracker contract. Due to Tacker's administration employees' inability to inquire or confirm bank account details for the debit order, Tracker used the expired banking details from 2013. Months passed, and no contact or query was brought to our attention. We first became aware of this situation when debt collectors contacted us. I contacted Tracker, and after numerous phone calls, I discovered that Tracker used the wrong bank account. I had to inform them! We resolved the situation, and on 2024-03-26, I paid the full amount of R1417.81. Since then, it has been a nightmare corresponding with Tracker. I've sent proof of payment four times to the following email addresses I received. *** and ***. We are being harassed with up to eleven calls per day and each time; I have to repeat the same conversations of the current day's phone calls as well as all the previous day's conversations, and still, after six months, this has not been resolved.
