Nightmare with Cartrak- totally *********

I have been a customer with the from 2016 when I want end to cancel my contract with them due to lack of services, I was sent from pillar to post, and kept debiting my account, when i return the Debit order the then threaten to list me, they I get am sms to say if I pay a certain amount the will give me 15% discount on the revised debit orders. on top of that they go and run another debit order that is no R200 more that what they had on the sms, not quite sure if they are regulated as they have no ethics at all, the regularity board needs to really investigate this company. dealing with them is a real nightmare. I would not recommend this company at all
