San Luis Rey Towing, San Luis Rey Towing and Auto Salvage Attempt to Collect Impound Fees from me for vehicle I do not own Oceanside California

Absolute criminals. I sold a car to a guy,  signed over the pink slip, did a bill of sale and filed a release of liability online with the DMV. The guy subsequently got His vehicle impounded. San Luis Rey sent me the bill. I called them and explained the situation. I sent them a copy of the release of liability and contacted the DMV. DMV assured me that my release of liability was sufficient to absolve me of financial and /or criminal responsibility for the vehicle. Then the guy that owns this place hires a collection agency to come after me for $1,800.00. threatening legal action. I can't wait. I'm going to file a small claims suit.
