We parked on private property for a shopping center but did not see any signs for a tow away zone. (Later we found out the signs were placed low enough to be hidden behind parked cars so they are not visible when entering in your vehicle) when we called to retrieve the car they demanded "cash only" so we called a family member to pick us up and bring cash when we arrived they showed us the paper work for the tow but the tow was never authorized by any propery managers it was only requested by "joe" also the "police tow in #" is required within 30 Minutes of the tow but my paper work says it was 1h 15mins which is another violation. They also charged me storage fees when they had the car for 1h 15mins and law says they can't charge storage until after 6 hours. What can I do? worth sueing?
