Poor/non-existent service from Netstar

My insurance for my new ly bought car requires tracking fitment by Netstar: this is the 3rd day in a row that my husband and I are trying to get this done. We hold on the line, we get through to inept staff who keep us waiting for more than 5 minutes, we are told our mobile numbers are not linked to the Netstar account, we are given the names of strangers who are linked to our account. In short, we are unable to get this tracking device arranged; we despair that - god forbid, one day we should actually NEED this tracking device in a n emergency; and we are wondering why our insurer, Outsurance, should be pairing themselves with a company with this service profile.
