I hate Comcast with a passion. Practically called me a liar to my face, and that 1800 ms ping is "perfectly normal." They wanted me to pay for their technician to come out and fix a problem that was very obviously theirs, but they insisted that it's all my fault. Only after I drop kicked them to the curb for something else did they send one of their salesmen over to try and sell me on it again, telling me that, "Oh, yeah, it wasn't your fault afterall. One of the central nodes was damaged."

Took a considerable effort to not punch the guy in the face.
