King Price fail to keep their promise

In December 2021 my car windscreen was hit hit by the stone from the passing vehicle. I submitted my claim but my car's windscreen still not been fix. The problem is they wanted to replace my car with generic windscreen. I informed KP that my windscreen will loose their warrent. It has to be replaced by the original windscreen. I send them an email from Opel but there was no communication from KP. On the 13/08/2022 KP sent me an sms saying that my claim will be cancelled. How can they cancel my claim whereas they did not fixed my windscreen. I have been a loyal customer to KP but when they need to provide as they promise, they treat me badly. They don't deserve even the one star that i have given them
