What to do if someone has your car towed off there property,even though that gave you permission to put it there....

Request a tow hearing with county. Info should be given to you when you pay to get your car out of storage. Take pictures of everything. Tow signs, their tow truck, the signs at storage facility. Research and look up local rules and state guidelines for tows. You will find a technicality that they did wrong. It’s the only way to fight it. If in Texas make complaint with TDLR.
