A lawsuit accuses Comcast of robocalling a customer "an average of once or twice each day" for nearly nine months to collect an "unpaid" bill—even though the woman had actually paid in full.

Kia Elder of Philadelphia filed the lawsuit in US District Court in Pennsylvania, saying the calls began in late September 2014, when a collector called her about a $527 cable TV bill.

"Plaintiff informed Defendant that she had paid that debt in 2011 and told the collector that she wanted Comcast to stop calling her on her cellular telephone," the lawsuit states. Despite this, "from late September 2014, Defendant placed cellular calls to Plaintiff an average of once or twice each day" and the calls allegedly continued through June 18, 2015.

The calls were automated, beginning with a message stating, "We're calling from Comcast," before transferring the call to a live representative, the complaint said.

Elder alleged violations of the Telephone Consumer Protection Act (TCPA), and asked for damages of $1,500 per call. The TCPA sets out a $500 fine for each violation, an amount that can be tripled for willful or knowing violations.

The suit was filed on July 10. Though the complaint is available publicly through the courts' public records system, Comcast told Ars today that "we haven't been served with the suit yet so we can't comment."

Earlier this month, Time Warner Cable was ordered by a judge to pay a robocall victim $229,500. In that case, Time Warner Cable placed 163 robocalls to the man over a 13-month period, with 153 of them coming after he had told TWC that it was calling the wrong person.
