The aggressive sales tactics of a door-to-door, carpet-cleaning couple have raised the suspicions of residents in northeastern Forsyth County.

It appears the man and woman have knocked on doors in neighborhoods in the Chestatee area offering carpet-cleaning services. They may also have tried to solicit business recently in Hall County and South Carolina.

Forsyth County Sheriff's Capt. Paul Taylor said he has not received any reports of the couple being cited for a crime here.

"We ask that anyone that sees suspicious activity, suspicious persons or vehicles, people coming to their door asking questions or having too much information about them, we would ask that they call the sheriff's office and we'll come out and investigate and see if we can locate these people and find out what they're up to," he said.

Meg Killingsworth, who lives in the Willow Bend subdivision, said a woman knocked on her door Tuesday night, shook her hand and called her by her first name.

The woman said she was trying to help her boss get his carpet-cleaning business off the ground.

Killingsworth said the woman told her the procedure was safe.

"She said, 'It's great for babies. You have a baby don't you?'" Killingsworth said. "Which signaled a red flag right there, because I don't know how she knew."

Killingsworth said she thinks the woman may have looked through the glass in her door, where she could have seen her baby seat or play crib.

She said she felt like the woman was trying to get in her house, though she did not invite her inside.

Killingsworth asked for a business card, but the woman said she didn't have one and that she was trying to get the business going by herself.

"Well then I thought that was a conflicting story," Killingsworth said. "She went from boss to this."

She told the woman she wasn't interested and closed the door.

She said the woman first presented an aerosol can as a gift, but took it back when the offer was turned down. The woman said she would give it to neighbors who agreed to let her in.

Killingsworth then called three of her neighbors, each of whom said they hadn't seen the woman.

"So I knew something was wrong," she said.

Killingsworth said the woman was attractive, appeared to be in her mid-20s and had long, brown hair.

The woman resurfaced shortly after leaving Killingsworth's house, at the home of her friend Jennifer Hester near Jot Em Down Road. This time a man accompanied the woman.

Like Killingsworth, Hester wasn't interested and turned the couple away.

Both women have reported the encounters to the sheriff's office.

Based on reports of similar incidents, Hall County authorities said, about three people were cited recently for operating without a business permit.

Reports published online by an Edgefield County, S.C., media outlet show residents there were also made uncomfortable by carpet-cleaning salespeople in October.

According to the reports, a couple in a grey, West Columbia Kirby vacuum cleaner company sales van approached residents and told them they had just performed carpet-cleaning services for their neighbors.

The couple's statements were found to be false and they were warned by authorities to be honest when soliciting business.
