Sewell Cadillac of Houston Doesnt Pay their Bills Houston Texas

I am an Accounting Rep.  for a small family owned  transportation company in Houston, Texas. Our company delivered two cars for Bradley Kerschen, at Sewell and were never paid for our work.  I am writing this review because we are at a loss. It has been over 6 weeks since payment was due and they have done nothing but give us the run around. I have been told numerous stories by both Brad and the Accounting Rep., Amy Rogers, such as  "checks are in the mail" , then a week later '...we never received your invoices', and the next week "...oh we didn't send payment because your insurance lapsed". All lies. I am hoping that somebody at the dealership, who cares about their companies reputation with their contractors, will see this and do the right thing. Its not like this is a lot of money.  We are done chasing them, but are just beginning to spread the word about how their company preys on small contractors like us. If this is how they treat the contractors for a outstanding payment of a few hundred dollars, imagine how they will treat a patron who purcahses a vehicle from them.
