MTN ****med me with faulty device/SIM card - Insurance declined claim - Issues false usage reports to substantiate no claims

I took an iPhone out on contract with MTN January 2024 - I took insurance with Admyntec. My account was paid in full and a few months later my iPhone was ******. Followed all procedures to claim. Insurance declined my claim due to my iPhone not being in use with SIM card (SIM card was in my phone and in use) escalated the matter to internal arbitrator at Santum, declined again, approached ombudsman for non life insurance, went for investigation - declined again however investigation revealed that the report that shows usage does not reflect iPhone at all, however there's calls received and made from the iPhone that does not reflect on the report at all. Referred back to MTN as conclusion is that the iPhone or SIM card was faulty and that's why when in the iPhone it did not show on the report. Calls and SMS and dates don't reflect in the report at all. MTN refers back to Admyntec, ma5er escalated with MTN legal and ICASA and Consumer goods ombudsman. ICASA says it's out of their jurisdiction. MTN acknowledges my email and doesn't respond at all, it's been months and emails sent every week, no phone number you can phone, no response on email. Stopped paying account due to not having a device, and no service from MTN. Credit is damaged beyond repair, held accountable for a service I'm not receiving. Seen many posts of this happening to other people, **** of the century
