A family in Nova Scotia’s Annapolis Valley has filed complaints against a company that sells medical alert systems, saying the company is taking advantage of seniors.

Clients of Seniors Connect can push a button to signal they're in trouble and a dispatch centre is supposed to respond.

But one customer's family is filing complaints with the province and the Better Business Bureau.

Elsie is 82.  We've agreed not to use her last name. She said a salesman came to her door and said her neighbours had recommended she buy a medical alert system.

"I know I signed two contracts but he didn't give me any," she said.

Elsie did write a cheque for $2,067.

She received a single handwritten receipt for a total of five years’ coverage.

"He was a fast talker, I told Matthew. He was a fast talker, he talked terrible fast and I couldn't grasp what he was saying," she said.

Matthew Sponagle is Elsie's grandson.

"It doesn't break down [Harmonized Sales Tax], there's no mention of an HST number, my grandmother didn't sign this anywhere and there's no indication of what the cost will be after this five years to continue the service," he said.

Sponagle said there was no box, no instructions and no explanation about what happens if there is an emergency.

The family wants to cancel the deal and get Elsie's money back.

Service Nova Scotia said the company doesn't have a permit for door to door sales. The Better Business Bureau said it's received three complaints this year about Seniors Connect.

The owner of Seniors Connect, Tom Fennessy, said he always leaves a contract. He also said he's committed to resolving complaints and providing a good service.

RCMP say people should not let strangers into their home and should always ask for documentation that a company is licenced to sell door-to-door.
