Heart breaking service

I really don't know how to explain how bad is the service I received from Iwyze, I was involved in an accident in June 2022, I had to call them every time for an update on my claim, I ended up asking to talk to someone senior since no one could give me any answer as to what is happening, he promised to get someone to call on Monday the 29/11/2022, that is when I got a call from a lady telling my claim is rejected, due to the fact that I did not disclose that my policy was cancelled due to non payment with my previous insurer, at the time I had nothing to disclose because I paid my premiums until I switched to Iwyze. no formal communication has been sent to me as we speak,
