I’m very disappointed in a company I have been with for over 10years!!!

my car was vandalized while I was away for the weekend . Car side scratch and seat had hole punch in them etc.. My gas tank was open with white sugar like fluid in and around it .

USAA adj said they would send gas off to be check and 3 week it can back neg . They told me it wasn’t sugar . I never said what it was because I didn’t know . They refuse to pay the claim !the seat with hole they said was burn mark but not melted or black mark etc.. the sad thing is we don’t smoke at all .the scratches they said came from someone walking by and rub it . This is the biggest BS I have ever heard or seen . This company have really let me down to say the least. I going to the repair shop to take my own pics before I contact my lawyer about some legal help!!
