Cannot get a straight answer!

Called Netstar to arrange unit migration from one vehicle to another on 10/11/17 - over TWO months ago! I have had to call back several times constantly following up ... being told one story to another... followed up again today without any end in sight as to when the installation will take place! My insurance company is going crazy as the vehicle has to be fitted with a tracking device to be covered under the policy. I have left a voicemail message for the Durban branch manager as well as email her directly. I am trusting I receive a response as to when this be resolved as they are more than happy to deduct the monthly debit order without providing the contracted service?!
