Extremely disappointed!!!!

Got a absolute hate against this company now, always had good service with them until now that I wanted to cancel my contract. It's started with I wanted to reinstall my tracker and I spoke to them about it they told me it would be R870 at that moment I wanted to do it but decided against it the next day, so I phoned and emailed them to cancel it, I spoke to probably 5 different people and everyone said it's canceled. Okay so now we are at the cancelation process. I told them please cancel it and they said yes it'll be R2700 about I said fine go ahead put it through a debit order on 30th of October. 30th came and they took their money, the next day they took another R1000 rand. I phoned them and they said it's for the reinstall, I told them I canceled it and I already canceled my contract. That's when she tells me that they can't cancel it and I must phone again on Monday so someone can assist me. Fine I let it go but now they took another R185, so they keep on taking money but my contract is supposed to be canceled. Keep in mind I they record all their calls so if they go back and listen there was nothing mentioned about extra money. So I'm very disappointed in Cartrack what if I need that money for something else because they can't give me a possible refund before Monday and even if they do it would probably take 2 weeks. I also had another instance 2 times now actually where my monthly fee goes up without warning so Cartrack if you see this I will NEVER do anything with you guys again and if it goes on like this I'll make sure to tell my people that has cars with you guys to also cancel!
