Dq track app linking nightmare

I bought a new car, added it onto my existing discovery insure policy, did the multi point check at a tiger wheel and tyre and installed the dq tracking device all on 24 July. It has been 20 days since the dq track was installed and I am still unable to link it to my discovery insure app. I have phoned discovery 4 times(about 2 hours in total) regarding this issue, everytime i get told that it is a backoffice issue that will be sorted out in a couple of days. The last time I phoned I was told I they would phone me with updates, it has been a week and nothing!!!!! What must i do to get some service or for discovery to be proactive??????
