Comcast Cable has fired two customer service employees who changed the name on the bill of a Chicago-area customer who made repeated complaints about her service to “Bitch Dog.”

The customer had made about 40 calls to Comcast during July because of repeated problems with a new digital recording box, according to the Chicago Tribune. During those calls, she was put on hold, disconnected and transferred to a Spanish-language line. Finally, her August bill arrived with the insult appearing in place of her name.

After a story appeared on the front page of the Tribune, Comcast apologized to the customer and issued a statement. “We are appalled by this treatment of our customer and want to extend our sincerest apologies,” the statement said. “We have identified those responsible for altering [the customer’s] bill, and they have been dismissed as a result of this incident.”

The customer declined an offer of two months of free cable and is waiting for her service to be disconnected.
