No Billing Solution

I had my Cartrack fitted in March. The first debit order was meant to go through on the 1st of April, it is now the 11th of May and to date there has been no billing. I followed up at the beginning of April to find out what was happening and then again in the first week of May. My call was taken by Nomsa who promised to call me back (and didn't). When I followed up with her she told me that I was still on a dummy account and I would have to be billed for the past to months in order to rectify the issue. She was going to send me an invoice on Friday - I AM STILL WAITING. My question is, if the car goes missing who is going to take respobnsibility for that? I have been following up and no one has attended to the matter. Can you fix this? Your lack of service is absolutely unacceptable!!!! <br> I want this settled or you can take your unit back, refund me for it and I will go to another service provider.
