pathetic, avoid at all costs

I have been a client for just over two years. In this time I have been threatened with non recovery of vehicle due to non payment (payment was debited every month) due to an admin fault on cartacks part. It took almost 2 months to sort this out with numerous unanswered emails, promises of returned calls that never happened and given the complete runaround when I phoned. the only time they responded when I posted a complaint on facebook. Then in August this year after an attempted theft of my vehicle I was informed that my unit was not working. I then had it replaced (at my cost). I was then double debited for this and this too took almost two months to be resolved and only after I threatened to take the issue further. After testing the unit I was told that that unit too was not working. After replacing it once again it worked for a day and when it was tested again I was informed it was once again not working. so I have had units in the vehicle that have not worked possibly for months yet I still get debited. Every time I phone customer "care" I get told a supervisor (Elmarie) needs to assist and yet the supervisor is never available. I get informed that the supervisor will return my calls yet this never happens and emails to customer "care" go unanswered. I have cancelled my contract with this company. Stay far away from them they are completely pathetic and have absolutely no clue what customer care means. The only reason they are getting 1 star is because there is no choice to give zero stars
