Pepco was largely dinged for the number and length of its outages. And the company saw a “shocking” decline in customer approval ratings in the last year, according to Business Insider.

The rankings were based on thousands of customer surveys by American Costumer Satisfaction Index.

Pepco beat out some stinkers including Time Warner Cable (#3), which recently aired pornography on children’s channels and United Airlines (#7), which charges customers baggage fees of up to $200 per piece of oversized luggage.

The rankings were filled with utilities, airlines, power and telecom companies. An ACSI official told Business Insider that these are generally not competitive industries, so customers have few options to jump ship.
