KIRKLAND, Wash. — A couple is suing Comcast after they say their home security system failed when intruders nearly killed their teenage son in their home last year.

They say their security system didn't do what the company promised. And they believe Comcast left them vulnerable on the worst night of their lives.

"They were going to play a game with him ... and the game would be that he would be fighting for his life."

The night that still haunts Leena Rawat came just weeks after her family moved into their Kirkland home in September 2013.

Never without a security system, they purchased one from Comcast immediately.

"And he check marked that this home is certified to be intruder proof," said Rawat.

One month later, police say two men were on a thrill mission to kill. They broke into the Rawats' basement window and ripped their 18-year-old son from his bed and tortured him, trying to cut off his arm and leg.

"He was full of blood from head to toe, with gashes," said Rawat. "He was in the worst situation possible that a mother wants to see her child in."

But what gnaws at this mother's memory: the security system, she says, failed them.

In a lawsuit filed against Comcast and their contractor, Pioneer Cable, the family argues they'd been promised a "secure network" — with which both the "stay" and "away" functions would keep the basement motion detector active.

That's why, Rawat says, the company saw no need to arm the basement window.

"I actually stood right in front of that window and I have a clear picture in my head where I said, 'Why don't you have sensors on this window?" she said.

In reality, she says, the basement motion detector was off. But in Comcast's contract, they waive all liability.

"If their argument is to be accepted, they could put in empty black boxes throughout the house and say, 'That's your system.' And then something goes wrong, and they say, 'We never promised you it would work,'" said Ken Friedman, attorney.

No one was sure, not even his doctor, that Deep Rawat would survive.

"I just say God was there that night," said his mother.

That's the reason she's willing to relive the nightmare in court, even as she relives it every day.

"It's been very tough. It was not a one-night thing. It's changed our life," she said.

Comcast's lawyers issued the following statement:

"We want to take this opportunity to extend our sympathies to the Rawat family. However, after a review of our records, we are confident that our home security system functioned properly."
