Netstar is a NO-GO!!!

WORST SERVICE EVER! I have a faulty Netstar tracking unit in my car, and have 7 reference numbers since 30 April regarding this. Everyday I get a call to say that I've been in an accident. After numerous times that we've reported it with reference numbers, no one gets back to us or calls back. I even email NETSTAR to cancel it and they gave us a reference, no further communication from netstar. I did, however, get an email from Mmeli Mgongo to tell me I should email someone else, as if this is my job?? I want this unit out of my car and cancel this!!! I only have it for a month and I am now GATVOL. I was prepared to give you a chance, and gave them till end of working day today to sort it out, was again promised that they will call me back today, but once again your team failed to do their job.
