Unfair treatment

I insured my Iphone and Iphone watch with this insurance company. I got ****** at Cape Town Station on the 21 October 2021. I blacklisted my phone and open the case at Cape Town Police Station. The insurance called to ask me to sign the affidavit for Mtn to give them information or location. Mtn does not have the records for the day firstly I was receiving sms and calls when I was at FNB branch in Cape Town, I downloaded the app there. and is not my fault. I insured my phone because I wanted a peace of mind now they taking me on pillar to post when they need to pay my claim. I trusted this insurance but now they prove me wrong.
