Television

I bought a 55inch tellefanken tv seton 16 August 2016 & took a 4year insurance cover on it. Which was to end on the 16 of August 2020. The Tv started giving me problems in June 2020 were it wouldn't switch on but at that time the country was under lock down & we were advised to no returns or exchanges from the Government. In October after the tv had not been in operation for sometime i managed to take the tv to the store & was called by 1 of the consultants on Monday & she told me she had successfully logged the call for my Tv & will update me on any progress on my tv. A few days later i was called by the insurance telling that they will not fix my tv coz my insurance with them had expired. I then asked them what i need to do next & they told me that it was in the hands of the store now & the store will call me & tell me what to do nex***** been 4 moths now the store have never called me & the still have my tv with them & I'm left not knowing what to do. Please help
