Cable television provider Altice USA has sued New Jersey’s board of public utilities over a demand it provide prorated refunds to customers who discontinue service in the middle of the month.

Altice is not subject to rate regulation by New Jersey because the Federal Communications Commission has declared it faces effective competition from other providers, according to the lawsuit filed Dec. 13 in U.S. District Court for the District of New Jersey in Trenton. The suit was prompted by an order from the board of public utilities, which wants to compel Altice to issue prorated refunds to former customers.
