Worst Brand Ever!!!!

I have had the worst experience with Telkom insurance, I lost my Iphone 14 pro in February this year and followed the claiming process which was successful, but was told that they are out of Iphone 14pro so they will have to upgrade me to an Iphone 15 pro and I must pay the difference of which I did, then they eventually sent me the Iphone 15 pro 2cnd week of march 2024. The iphone 15 pro only worked for 2 weeks and just switched off, it wouldn't charge or switch on again. I took it in for diagnostics and repairs and I have been waiting for it since then. No communication whatsoever I'm the one that has to call almost every day and be sent from pillar to post, calls being dropped at with no help or direction. I have been paying on time for a phone I do not have and using. I am beyond frustrated, my patience has run out. I have never been late in paying their premium and insurance but I'm appalled with the service I have been receiving. It's been 8 months now without a phone. No one is telling me anything concrete. I want my money or phone back!!
