Bad service and lies

I have a contract with vodacom and my phone I insured. 2 months ago I got ****** and lost my phone. Vodaclm doesn't want to replace my phone because the simcard was last on the device 8 days before incident instead of 7. Tbeg keep on making promises to get back to me and they never. It's been 2 months with no proper phone .when i call their customer I never get an answer. They say they escalated the issue but no one ever gets back to me. Every month om paying for a ghost device Worse thing. They keep on extending my 24 months contract I am do fed up and I require something to be dkne
