It would be much easier for you to describe the circumstances under which you were towed than it is for us to interpret the scope of the law as it stands and all the ptrovisions it may or may not cover.
Your description should include all facts related to the incident including the time you parked, the time your car was towed if known, the time you retrieved your car if you have done so. The details from any forms you were provided. The authority under the tow or the legal reason why they towed it and who the tow was authorized by. A general description of the nature and purpose of the parking lot and where you were at the time you were parked there.
And so you got to the lot was unable to find your car, looked up on the sign and saw no phone number, you called the local police, right? And were subsequently informed that your car was towed, were you not?
Describe the sign... What does it say and how many inches does it measure? If you're going to make any claims you'll have to obtain pictures of the signs and where in particular they are located on the property. Is this possible?
