Claims not being attended to while my vehicle becomes more dangerous to drive

I am currently a policy holder with insurer MiWay I had a puncture and logged a claim on for the incident, they told me I was covered and sent my car to be assessed by their approved panel beater. Once the assessment was completed miway had become as scarce as water in a desert. I called a few times a day, everyday, left enquires on the app to be called back. The consultant responsible for my case has never answered a call or responded to an email sent by me. Eventually, when they did call me, I was told that the quote was approved and that the panel beater would call me, which did not happen. They then disputed something on the quote and said they would email me the quote they received from the panel beater and then call me back within the day. None of this happened. I went through call Centre once again and another consultant told me they decided to pay me out, an amount not equivalent to the quote, without consulting me first. They said they would call me, and again nobody did. I called through call Centre the next day and another consultant tells me another version that my quote only got approve this current day, so why was I **** to about my quote being approved the previous day. I was also told the assessment report was sent on this current day and that's why my claim was approved - but if that were true, why was i told my claim was approved the previous day. I called the panel bester to find out and they informed me that the claim was not yet approved. In this time that miway is deliberating my vehicle is using a biscuit Tyre, which is causing even more damage on my vehicle. My car does not have a spare tyre and I am a single female driving alone. Today for example I have left several enquires and I have not yet received a call from miway. I am very dissatisfied with the service, my insurer should make me feel at ease but instead I am fearing for my life in my vehicle that urgently needs to be fixed. Miway promised me service and value and in the past week I have not received either.
