My opinion park behind them. That's what they get 4being in your spot. I just wouldn't have them towed.
I tried calling the last time someone parked in my spot and they said only the office can call them. We called the office, submitted a request online, and then an email but it still took 4 days for us to get our spot back. But yeah, the entrance gate will have the towing company info!
Look on the entrance gate for the name and number.
