Theresa Tang is afraid to show her face on camera after hiring a group of pavers who don't seem to be who they said they were.

Black Top Paving showed up at her door offering to resurface her driveway. Two weeks after they finished, it's already cracking, and the address listed on Black Top's business card is false.

Tang describes the men as blond, stocky, and speaking with thick U.K. accents.

"On his left arm, all the way along his arm, (there was a) big scar, deep scar," Tang told CTV News.

"I wish I had taken his picture, but I didn't."

Based on an investigation by CTV News, Burnaby RCMP are investigating Tang's complaint.

"We're just in the process of speaking to that person so see if there is a criminal element," Cpl. Brenda Gresiuk said.

Meanwhile, the Better Business Bureau has issued a warning about another company called Advantage Paving.

Once again, this company involves men with strong U.K. accents.

Lynda Pascecreta of the BBB says that while company names may change, the approach is always the same.

"Red flag number one is the knock on the door," she said.

"They'll approach people whose driveway is a little rough looking and they'll say a neighbour has gone with this."

Once the job is done, they demand cash on the spot.

"They'll even accompany a person to an ATM to get cash out of the machine," Pascecreta said.

When CTV News reporter Chris Olsen called Advantage Paving, he reached a recorded message, and received no return call.

Their address in Surrey is an undeveloped lot filled with cars.

But now with Google's Street View, anyone can have a look at an address right from their home computer -- another way to prevent a problem before it starts.

And police have some advice for consumers before they hire anyone to do paving work.

"Ensure they are bonded, licensed and are registered with WorkSafe BC," Gresiuk said.

That can protect you if a worker is injured on your property.

CTV News was able to reach a man calling himself "John Ward" at Black Top Paving by phone, and asked him where his company is really located.

His answer: "I don't know if it's any of your business. I do a bit of work under the table. I work hard for me money."

But that leaves Theresa Tang with no way to track down Black Top Paving to get them to make good on their promised five-year guarantee.

In her last conversation with them, she says they told her they were coming back to fix things in six months.

She's doubtful about that. "In September, I won't be able to find them anywhere."
