Cartrack the biggest *****ster

Car track are big *****sters, *****ing my money from my bank account. They go into my account and deduct any amount they want anytime. i am really ****ed off with this company because i do not have any agreement that give them the right to take my money as they please, I requested them to cancel the contract i had with them two years ago if not mistaken because i do not have a car anymore that was insured with them, why must i pay for something i do not have, instead of cancelling the contract they taking my money as they want, i am not sure if we sharing my bank and my money, i am really confused. i want my money back . they don't mind taking R935. 00 and R522 in one month and i don't have any agreement giving them the right to do that. i want my money back asap.
