INDIANAPOLIS — Patricia Schnepf was excited to attend P!NK's concert at Lucas Oil Stadium last month and wanted to make sure she had a place to park so she paid ahead for a spot in a lot at South Street and Madison Avenue. She paid $58.30 to park there and her receipt said the parking would be good for "2 hours after event." Schnepf attended the concert and pulled out of the lot a little after midnight.

She said she didn't think twice about it until last week when she received a bill in the mail. “We got a parking letter that we had violated the terms and that we owed $82 to be paid within 30 days or they will turn it over for collections," Schnepf said. “I thought, 'Well, we have a receipt so it’s no worries. I’m gonna dispute it. They got a link right here to dispute it. No problem. I’ll dispute it and I’ll walk away.'” Photo of Schnepf's bill. That bill came from Parking Revenue Recovery Services (PRRS), but when she disputed the charge she said it didn't do much good. “They declined the dispute and said they would give us a $20 discount but we still had to pay it within 10 days to take advantage of the discount," Schnepf recounted. "And there’s still a five-dollar convenience charge for paying online.” Schnepf reached out to FOX59/CBS4 about her dilemma to see if that could help. FOX59/CBS4 discovered that PRRS doesn't sell the spots themselves but simply enforces compliance. They provide that service at numerous Indianapolis parking lots and garages. They do so by using artificial intelligence cameras that track a driver's license plate when they enter and leave the lot. PRRS is headquartered in Colorado where they have been found to violate consumer protections by wrongly charging customers and leaving them with big bills, according to the state's attorney general. The company settled with the state and paid $106,000 in fines. PRRS has had documented issues in other states as well, according to news reports. A company spokesperson told FOX59/CBS4 on the phone that they are given the parking expiration time by the company that actually sells the parking spot. In this particular case, it was ParkWhiz. Figuring out when an event ends and then adding two hours to that is not possible, the spokesperson said.

"I think that they are playing a numbers game and if you send a letter to everybody and a fraction of them pay, you’ve made a lot of money for the price of a stamp.” The spokesperson said the company would void Schnepf's bill along with anyone else who may have been wrongly charged. They also said they have contacted the lot operator to ask them to change the language that promises parking for two hours after an event and to simply stick with a definitive time. FOX59/CBS4 will stay on top of this story and see if PRRS follows through.
