Unhappy customer

I have been with cartrack for years, I have finished the 3 year contract with them, and by surprise , they didn't notify me that my contract with them its over, they keep on debiting me, 1 day I checked my contract with them, I saw that it was over, they have been debiting for some months, and I reversed the debit orders some of them, and they called me, saying I'm in arrears I need to pay, so I told them that i no longer have a contract with you guys, and they say the agent did explain that after 3 years, it will automatically be on month to month, I said no, the agent didn't explain anything like that.

What I remember is that, the agent said to me, after my 3 year contract, someone will call me and ask if I should go with month to month, so no one called me. So I asked for the recording a full recording, they sent me 5 minutes of the recording, but I remember well the call did took 5 minutes maybe it took 35 to 45 minutes.

I emailed them again asking for a full recording, guess what, since 2021 April asking for a full recording, till now now 1 has sent that recording, but they keep on calling me that i must pay the out-standing amount, and they still going to do debit in my account, and i always reverse it cos i told them not to go into my account, i told so may agent calling me every month, that I need the recording they all promising to sent till now from 2021 April, now its 2024 July the 7th. Last agent that called me and promised to send the proof It was Kholofelo Mamietja and before that it was Lufuno Mfenyana they all promised to send the recording , and the other who sent me email for issue simple Summons its Puseletso Manyanye

I'm going to change my account number.. cos I'm tired of them every time I have to do reversals , and bank is charging me for each reversal every month
