Time Warner Cable has been ordered to pay a woman $229,500 (£150,000) after a judge ruled it had harassed her with automated calls.
Texas resident Araceli King received 153 computer-controlled "robocalls", which continued after she had asked the company to stop.
US district judge Alvin Hellerstein said Time Warner Cable had acted in a "particularly egregious" manner.
The company said it would review the ruling before deciding how to proceed.
Making unwanted automated calls is illegal in the US, and companies breaking the rules can face a fine of $1,500 for each call.
Mr Hellerstein said he had tripled the penalty for Time Warner because it had made 74 calls to Ms King after she had registered her complaint.
The judge said any company that "robodials the same person hundreds of times over many months without pausing to wonder why it cannot reach him" could not complain about the higher fine.
