Bad service and non payment of claim by Oaksure/Renasa

I have had this comprehensive insurance for 7 years and when I made a household claim I was very dissatisfied with the service. I put in the claim in October and there was nothing done after the assessor came, where I had to write numerous emails and made calls where they said they will get back to me and never did. On 16 November 2022 the underwriter Renasa sent a letter that they will pay out R5000 to replace a tv worth R12000, fridge worth R18000, and other household contents. I complained. They said they’ll get back to me, they review claim form and other documents…I have never had further feedback, I’ve emailed and called, it’s now March 2023…..I’m so frustrated, I don’t know if to cancel insurance with this claim pending, because what is the point of contributing for so long and when you need help it’s this disappointing.
