Unresolved Claim

I want to express my disappointment and frustrations on both my service provider and my insurer. I have bought my daughter a phone I submitted proof of payment when I app**** for the insurance, I tried to blacklist the phone when it got lost, my insurer said there is no data. My insurer closed my claim after submitting all the documents with a reason that documents were not received. My service provider closed four calls that I have logged . Am frustrated at the service that am receiving, having an insurance should ease my frustration after the loss of the device, instead I have more stress even my premiums are paid up to date. I logged 4 cases with cell c ***, ***9,***, *** plus a reference number of a call that took 54min ***. i my insurer can not find a way to resolve this query with my service provider then they my refund me all the money that i have paid.
