Comcast
What do you do if your brand name is associated with the worst customer service in the U.S.? That was the problem facing cable and internet provider Comcast, which was consistently considered to be one of the worst internet service providers in America during the 2000s and 2010s.
Comcast became Xfinity in 2010 and most consumers didn’t notice. There was simply a new name for their terrible service. But Comcast didn’t go away completely. Comcast Corporation owns AT&T Broadband, NBC Universal, Sky Group, and DreamWorks Animation, among plenty of other companies.
