BRIDGEVIEW, Ill. — Some attendees of the inaugural Sacred Rose Music Festival noticed charges in the thousands on Monday.

The festival, held outside SeatGeek Stadium in Bridgeview, took place Friday through Sunday — but was canceled on the last day due to inclement weather.

Several attendees woke up Monday to a variety of pending charges after purchasing drinks.

Multiple attendees WGN News spoke with were charged over $1,000 and one said two of their friends were charged around $3,300 and $4,300 respectively.

After a firestorm on social media Monday, the festival said on Facebook Tuesday morning that SeatGeek Stadium, the vendor who ran beverage sales, had a “configuration error.”

SeekGeek Stadium said they are reversing all of the charges within “3-5” business days.

Rob Collier, of Milwaukee, either had the choice of canceling his card or contacting SeatGeek Stadium.

“I could cancel my card, get a new card or contact SeatGeek Stadium — and I don’t want to cancel my card,” Collier said. “So I tried going online to talk to SeatGeek Stadium to no avail.”

Others had no choice to cancel their credit card and some felt uneasy about the point-of-sale system used. Attendees said beverage workers had them say their tip amounts out loud and then the workers entered it in themselves. Previously, an attendee told WGN News some people were accidently leaving large tips on tablets due to an issue over decimal points.

Caroline Woods, of Chicago, said she only attended the festival Friday and noticed the real charges and subsequent tips over the weekend. Then on Monday, she woke up to a $1,085 charge.

“My first instinct was ‘oh my God, there was someone there trying to steal credit card numbers,'” Woods said. “It felt really violating and was scary.”

The experience made Woods question if she will bring a card to the next music festival she is going to.

“I’m going to Riot Fest in a couple of weeks and I’m going to bring cash for everything,” she said.

Despite the headaches Monday, the attendees WGN spoke with did say they had a good time with the live acts and understood why the festival had to be canceled Sunday due to weather. At this time, it’s unknown if attendees will receive refunds or partial refunds for the cancellation.

Phil Lesh’s and Jeff Tweedy’s “Philco,” the War on Drugs and Umphrey’s McGee were some of the headliners for the inaugural jam band-style festival.

In a Facebook post showing SeatGeek’s statement, Sacred Rose said they will “have more to say soon on other matters, but wanted to make sure everyone knew this will be fully resolved.”

SeatGeek Stadium’s full statement, issued through Sacred Rose, is below.
