Myway, there is nowhere to hide, pay, we pay every month

My wife and I lodged a claim with myway in July when technicians at Ronnie's realized that there was water leaking from the roof to the floor. They told us that the leak was caused by the dent next to the sunroof. Miway started to try and get some getaways, they started by contesting what the technician suggested that the leak was due to dent and said it was due to wear and tear which they do not cover. They sent an assessor which asked them to demonstrate that water was due to the dent, then we were sent the report and they told us that they recommend that the car be a write off, since water may have caused damages on the wires of the car which are situated on the floor. They sent the documentation that we need to send them settlement documents since it's a write off which we did. Immediately after that they changed their tune to say hey guys we are no longer considering the car a write off, what miway is gonna cover is the dent on the roof then the water damages which caused by the leak as a result of the dent, will be payed for by us. They claim that, we should have stopped the water from coming in immediately after the accident that caused the dent by reporting it to them. We do understand that its difficult times for the insurance companies, they are not making money as they used to be because of the pandemic but still they can not come up with such stupid reasons not to pay or to payless. The dent happened and water went in through the dent, now why fix the dent and not damage caused by the water from the leak? How are these two damages separatable. They even make dumb theories that there is no way that the dent happened when it was raining meaning it happened and waited for a rain. The people who called me seem to have been told what the outcomes should be but they cannot convince even my 6 year old with what they say.
