Inefficient service bordering to thievery

My house and it's contents are insured by Iwyze for more than 10yrs. My home was burglered and things amounting to R50.000 plus were ******. When I registered the claim, the company sent me from pillar to post requesting things from Apple store that they knew well that Apple devices do not have. I was given an inventory schedule in which I have to list my current household items and their amount.After I submitted I was told that the company had approved 32000 plus for the ****** contents. But they informed me that the inventory schedule shows that I have been shot paying them hence they are going to pay me 60% of the amount approved which amounted toaround 12.000 which is the amount that barely covered only 1 item of my ****** goods. It was very painful but I took the blow with graciously. Above all this emotional trauma I called iwyze and requested that they review and adjust the amount so that I get 100% cover. The lady consultant I spoke to kindly requested that I email her the current inventory sa as to adjust my premiums as soon as possible. When the lady failed to come back to me, I decided to call after 2 weeks. Another consultant lady informed me that their IT department has a glitch they will assist me when it is resolved. My question to the lady was that first the failed to inform me, secondly what if again my house is burglered while such a giant company that has no glitch when it comes to collecting premiums, who will be responsible for the shot fall. Iwyze was once super efficient Whose service has decorated to an extent that I question my sanity in being faithful to such poor uncaring as well as clumsy service company.
