(CNN) - Papa John's pizza has been delivering more than just pizza.
Customers nationwide have filed a $250 million class-action lawsuit because they say the popular pizza chain has sent out a half-million unwanted spam texts.
The messages offered pizza deals, but some customers said they got 15 or 16 of them in a row, in the middle of the night.
One of the plaintiffs said Papa John's never asked permission to text the advertisements, which was banned to the Telephone Consumer Protection Act of 1991.
The plaintiffs are seeking $500 per text, but could get up to $1,500 per text if the jury rules that Papa John's willfully broke the law.
The company's corporate office says they were not involved because the lawsuit involves a small number of their franchisees.
