Unsettled Claim and no communication in more 5 months

On 23 September 2019 I wrote an email to Auto and General Policy No: *** reporting a fridge freezer that had packed up. I got an automatic response that informed me someone would be in contact during office hours. My fridge had packed up no one contacted me I sent another email on 26 / 09/2019 again no one was in touch. On the 15 October 2019 I wrote a follow up email now stating it will be a month since my fridge freezer packed up. Eventually they sent an assessor who took the fridge away about a week later I got a call that informed me they were giving a settlement voucher. Someone else took the claim over and she told me the voucher would be a value of R8500.00 and I immediately said that cannot be possible because when the fridge was bought in 2014 it was R8000.00. She then told me that was the settlement figure and she asked me if I was taking the voucher or not I told her I needed a replacement value of my fridge of which I do not agree it is R8500.00 therefore I do not accept the voucher . She promised to come back to me and never did I tried to call and email but never got hold of her. I have since asked my Niece to follow it up and sadly she always told me someone will be in contact with me and no one did sadly. She even said one day "You are a very patient person” It has been six months now or just over 22 weeks I do not have my fridge no my claim settled. How does one manage without a fridge for such a long time yet they took home content for such? I had in the past week asked my niece to inform Auto and General "I would like to have my fridge back that was taken by an assessor and that I be compensated for such an inconvenience. I went out and bought a bar fridge which has not been helpful through the festive season up to now Again what an inconvenience!!!! Oh another thing I told them the fridge for the amount they were settling my claim with is of such a low quality I would not buy that fridge at any given time.
