Insurance company slaking

I had my 2006 chevy colorado stolen on dec. 23, 2007 from the backyard of my in-laws house. It was found 11 hours later in the marshes and it had water all in the cab and a water line that reached the top of the bed. The police said they had a string of thefts lately and it was possible that could be what happened. I had left it unlocked since it was a safe place(so i thought) and i always had my spare in the glove box since i had a history of locking my keys in. nobody knew this but me and my wife. i was told i would be contacted by an adjuster by jan 1. well i didnt hear from him till the 4th, then i was told i would be contacted by an investigator by the 4th. that didnt happen untill the 12th. on the 25th, they told me that they chose to do an EUO and i would be given a phone number for the attorney to set up my appt by the 28th. today is the 4th of february and i have not heard from the since. I had looked at getting a replacement vehicle the whole time and was told i couldnt get a letter stating they were taking over it untill after the investigation. well, on the 9th of jan i found a vehicle and the dealer called and they sent the letter. so on the 25th they said they wanted to go thru an attorney, even after i got a letter saying i had no interest in the vehicle anymore. I spoke to a military attorney today and they said i may want to look into suing the company. any suggestions or advice. Im also getting ready to go on deployment to afghanistan and when i leave i cant do anything.
