****med by Cartrack and they continue to do so

I have cancelled Cartrack 4 years ago but whenever there's money in my account they deduct, even today they just deducted R240 that's what they do randomly and they refuse to pay it back. I'm tired of complaining about 1 thing over and over because even their call centre is kaak no one wants to take responsibility or pay my money back,I'm sick and tired of this behaviour. IM NOT WORKING I CANCELLED YOU LEAVE ME ALONE PLEASE
