St Mary's Motors odometer inconsistencies Lexington Park Maryland

I purchased a2003 toyota sequoia from St Mary's Motors, started having electrical problems, brought this problem to their attention but they said it was not covered, so upon tracking down the problem l find that the instrument cluster had been changed. I then became suspicious so I run a car fax report and found that my suspicion was confirmed.

In 2009 the last true odometer reading was 227, 853 miles.in 2010 it showed up as 136, 190 miles .When I purchased this vehicle it had 187342.I was not informed by them that the odometer had been changed, I bought this to their attention as well, I was told by the GM to let sleeping dogs lay, sounds to me like you have something to hide, this vehicle has to have atleast 300000 or more on it.Do not buy a vehicle from these people, they are as crooked as they come.
