if you can, stop payment on the check.
DO NOT LET THESE GUYS GET YOUR STUFF!!!!!
Once they have your stuff, god help you after that, they will jack the price up 1000% and hide it until you pay them.
Do everything you can to recover your deposit, call the police, threaten lawsuit, stop payment the check, call the bank and report fraud, do not deal with this company. Once they get your stuff in the truck, god help you after that
