Incorrect accounts debited and incorrect amounts taken

Tracker and their *********** accounts department are really going the extra mile is putting that pride into *****ing their clients over. I had a contract for a Polo vivo which ended in June 2024 and called to cancel, they transferred me to their retentions department who managed to retain the contract on a month to month basis and also were instructed to move the account over to my daughters name and run the debit on her account, I was informed that they would call her do the necessary, move the Polo to her name and debit her account and then I requested they call me back as my intention was to add another vehicle Volkswagen Golf as a new contract. When they called me back they assured me that the account was moved no more debits will be taken from my account for the Polo Vivo and to my surprise they run a debit on my account and my daughters account for the month of June 2024. Amount taken from my account for the Polo Vivo was R247 which was incorrect as the new amount for the month to month contract my daughter agreed to is R179 plus R20. We contacted them numerous times and they continued feeding us lies that they have moved the account and that they will now credit my account with R247 which they never did for the month of June 2024. July came and they debit my daughters account which should be R179 plus R20 and they take R332, run a debit for the same vehicle on my account as well for R247 yet send me a credit not that my account should be credit with the R247 which i am yet to be paid back into my account. Now I call in and speak to someone who states they will now speak to their manager to correct this and find a way did could not find for the first 7 calls we made regarding this issue and they eventually drop the call on me after holding for almost 30 minutes. If there is anyone of this platform that could advise me as to how I can now go about getting this service cancelled for my Golf as my daughter has now called in to cancel the Vivo as well please advise me how I go about as these idiots are in bridge of contract with regards to how they run debits on incorrect accounts yet I have a free 3 month subscription of the Golf and getting debited for a polo which they were suppose to run on my daughters accounts and still manage to mess that up as well and debit her incorrectly. Hope tracker takes pride in how bad their customer service agents also handles calls showing how they lack in knowledge regarding their product they sell people, GOD forbid something happens and I call them to track the vehicle I most probably will be told they cant establish a signals cause all their agents I spoke to thus far seems to be having signal issues
