A Queens man needed a doctor after a house call from a surly Verizon repairman who pummeled him — and never fixed the problem, according to a lawsuit.

Robert Benjamin pounded Aubrey Isakson, 37, after the suspicious customer — told earlier that the repair wouldn’t require access to his Sunnyside apartment — demanded ID and wouldn’t let him inside, the suit filed in Queens Supreme Court charges.

“You want to know my name? Here’s my name,” Benjamin snarled, slapping his ID card into Isakson’s face, according to Isakson’s account of the December 2008 confrontation.

“The guy essentially snapped. He cold-cocked me, hit me two or three solid shots to the head while my hands were down,” said Isakson, a limo driver.

He said the pounding bloodied his face and broke his glasses.

But things got uglier, Isakson said, when Benjamin squeezed him around the neck and pressed him up against the wall.

“He’s prepared to kill me,” Isakson said. “That’s all I could think of.”

Isakson said he broke free and ran down the stairs — fracturing his ankle along the way — to get help in his building’s lobby.

One of his neighbors, an off-duty cop, grabbed Benjamin, who had chased after Isakson.

Benjamin was arrested and charged with assault.

But prosecutors offered to dismiss the case if Benjamin agreed to stay out of trouble for six months — despite assuring Isakson there would be no deal, Isakson alleged.

“According to what I was told, there was an error by the DA’s staff,” Isakson said. “They’re giving this guy carte blanche to do this every six months.”

The Queens District Attorney’s Office, citing the pending litigation, declined to comment.

Isakson’s lawyer, Marc Albert, said every company has a responsibility to screen employees.

“This is especially true with Verizon because of the level of interaction with customers,” Albert said.

Verizon spokesman Rich Young said the company has “zero tolerance for any sort of unethical or illegal behavior” and noted Benjamin was not convicted of any crime.

“In the months since this incident, his conduct has been blameless. As a result, we will not take further action,” Young said.

Benjamin did not return calls for comment.

Two days after the alleged beatdown, Isakson got a call from the Verizon technical service department.

“We think we figured out what the problem was,” Isakson recalled them saying. “They didn’t even need to send this guy.”
