omnisure group llc Ripped me off for 1400$ false insurance repair chicago Illinois

I was notified by a warrenty company Called Omnisure group that my warrenty on my car was about to or has run out.  A year later my timing belt went and needed repair. I notified the Company Omnisure and they said that They would send and adjuster out to verify the repairs.  The adjuster came and its been two weeks that I have been getting the run around.  The car dealer was gratious enough to lend me a car for a week and a half while my car is in repair. The car repair service representative called and said I had to make a decision on what I wanted to to because the car insurance company Omnisure did not make a decision yet.  They told me that I sighned a document saying that I had to have repair reports or maintanance records they never told me that and they never sent anything for me to sign that was a complete lie.

So I went to Jiffylube and gave them the last two oil changes.  I did a few myself and have to record.  Now two weeks later with my car apart in the repair shop they tell me that if I can produce two more reciepts then they have to close the claim I will get denied.  Meanwhile I had to agree to pay the repair shop 3300 to fix my car.  I didn't put to much pressure on them even though i have, after the fact googled all the negative reviews on this happening to so many others.  Why a real company would have made sure the documents are in order before they proceded with taking my engine totaly apart.  I have read so many of the same stories about the persons car torn apart and now the consumer is stuck with the bill. How are these people still in buisiness?  Who controls things like this to protect the consumer?
