Netstar App not functional

A technician was sent out to replace the unit in my car on the 10th of June after I informed Netstar that my vehicle was not visible on the App as well as none of the information I was able to view before. It is a week after I have been calling the call centre and being informed that the services need to be activated, however my vehicle is still not appearing on the App. This really concerns me as it means that I cannot use none of the App support of functionality that comes with the unit. Netstar, can this be sorted out please.
