Absa unauthorised debichecks

Absa has permitted cartract to debit my account different amounts on different dates sometimes 3 times a month R914 on debicheck without debicheck mandate being sent to me and absa charges me R200 per unpaid debit order of there is no money,this has been going on for more than a year now...

On the 15th July again they were debiting R850, on the 22nd June they took R914, on the 23rd June they took R914 on the 1st June they took R914 in my account on the 15th May they debited R914 they debited 3 times in June alone.

I feel less protected as absa current account client, everytime i have to move my salary to another bank around midnight if I forget cartrack will debit as it like...

I have no agreement with cartrack to debit my account whether on normal or debicheck,my contract with them was taken to attorneys 2 years back but they are doing it, absa is telling me they cannot stop this I have to talk to tracking company and cartrack is telling me they have automated system that takes money in my account whenever there is money...
