A Vancouver driver is honking mad after her vehicle was towed away from a paid-for stall in an underground parking lot.

Tegan Woo said she paid for a stall in the London Drugs parkade in Vancouver’s Olympic Village a few weeks ago.

“I just entered the ‘48’ for my parking stall, chose ‘flat rate’ for the whole day; it charged me and printed out the receipt,” she said.

But when Woo returned to her parking spot, her car was gone.

“I was really confused because there was no signage saying I wasn’t allowed to park there,” she said.

Woo said she even took pictures to prove the stall wasn't labeled as off-limits.

She later found out the space was an unmarked visitor stall for the condos above London Drugs. A condo concierge reported the vehicle because it wasn't registered.

Woo said she was one of four people whose vehicles were towed that day. Two people have contacted CTV News claiming their vehicles were towed from the same location.

Now the frustrated drivers are complaining to the building and Impark, the company that operates the lot.

A strata manager said the condo isn’t responsible for the issue and that the blame lies solely with Impark, adding that he has also lodged a formal complaint with the company.

He said that the Impark ticket machine allowed drivers to pay for spots that it shouldn’t have.

“The Impark machine should not accept those stall numbers that are not rightfully assigned to them,” he said.

CTV News contacted Impark Thursday, and the company promises to refund the towing costs for anyone affected by the mistake.

They said it was an oversight and they were unaware of problem, but will be fixing the machine so it doesn’t sell tickets for reserved condo visitor stalls.

Woo, who paid $98 to recover her car and $10 to park all day in the lot, said she also blames the strata for not marking the spaces as off-limits.

“I have a hard time believing that no one has called them about it in the past. I don’t know how long they’ve been unmarked and people have been getting towed.”

The condo has since put up signage in the stalls indicating they’re reserved, but the Impark machine was still issuing tickets for the spaces on Thursday.
