Rejected Claim by Cartrack

Cartrack rejected my claim for vehicle car loss, they literally said I should wait 60 full days before I could do that as they are doing their investigation on the vehicle loss, my car got ****** on 22nd of June 2021 at a Mall during the day, CarTrack claims they tried calling me but they never called but could not get a hold of me, they never tried calling the alternative number to at least alert that the car is tempered with, after the 60 days, the reject my claim stating that I should have claimed on the first 30 days of car loss, I explain to them I did want to but was advised only after 60 days I will be able to claim, it's been 90days already and I tried all avenues for them to actually give an x amount if car not recovered or get same vehicle with its retail, but nothing as of yet, please I need help to bring this to attention and if theres anyone who experienced my current ordeal can tell me what to do please. This matter I even escalated it to their CEO complaints department about rejected claims still they rejected it.
