Long time to process claims

I was involved in an accident on the 18th of February this year... The investigator contacted me for some consent form and other documents such as police report to send on the 23rd of Feb of which I did sent... I was told the investigation will take 10 - 15 days after they will contact me.. Because I was in hospital I gave them a full month and when I called they claims lady told me she is awaiting the investigator report... I waited for another month until I decided to call.. And again I got the very same respond that they are still waiting for the investigator report... Worse thing is that they are still deducting my money even during their delays... Last week they called me and told me they found out I was above 100 when the accident happened and they send the case to hollard claims forum... Surprisingly I'm been treated like a suspect in these whole thing and it's been more that 2 months now... I'm frustrated
