Comcast’s reputation is officially in the crapper.

A customer was shocked after the cable giant called her husband an “a- -hole” on their cable bill, apparently in retaliation for canceling service.

A Spokane, Wash., resident named Lisa Brown said after she called Comcast to cut her bill, her husband’s name was changed from Ricardo Brown to “A- -hole Brown.”

Even worse, Comcast wouldn’t change the name despite her calls and a visit to the office.

Comcast finally apologized after the incriminating bill was posted on Elliott.org, a consumer advocate blog.

“We have spoken with our customer and apologized for this completely unacceptable and inappropriate name change,” Comcast said in a statement. “We have zero tolerance for this type of disrespectful behavior and are conducting a thorough investigation to determine what happened.

“We are working with our customer to make this right and will take appropriate steps to prevent this from happening again.”

The nation’s biggest cable provider is still awaiting regulatory approval to merge with No. 2 Time Warner Cable in a $45 billion deal that will create a cable TV colossus.

Both Comcast and Time Warner Cable consistently rank near the bottom of customer satisfaction surveys. Comcast, in particular, has struggled with a string of embarrassing customer service gaffes.

In July, AOL executive Ryan Block posted an eight-minute call with a Comcast customer service representative who argued against Block’s dropping his Internet service.

The call went viral on the Internet, with droves of customers sharing similar complaints.
