Admin Plus Insurance rejected my cell claim due to no forceable entry to my car.

My phone was ****** in the car on the 15th Octorber 2021 which I suspect remote jamming since they was no forceable entry or broken glasses. I did follow the procedure of reporting the case got the affidavit also blocked the phone and filled the claim form. However the insurance rejected my claim saying they was no force used to gain access to my car therefore they don't cover such incidents.
