Really Fed Up

I'm really fed up with vodacom now... In March 2020 I app**** online for insurance. I was never sent any documentation and was told if I did not receive the paperwork to go in store for it. Unfortunately Covid 19 happened and everything was closed. In June my phone fell and screen cracked... I called vodacom and was told there is no policy. I then got back to work and saw all my invoices from vodacom with the charge for insurance, today calling them, the policy was found but now I can't claim as they have a 7 day policy yet in June when I called there was no policy.... So please help me understand what to do now...cause it's not my fault that only today they found my policy yet I called after my phone broke. This is like the 3rd time that vodacom is de*****ing me... First an unauthorized upgrade, then charging me for a phone I returned and now a insurance claim not able to be processed... Yet I've been with vodacom for many years. And I have 2 contacts with them. Really had enough now.
