Interesting.....after submitting last comment an ad for xfinity popped up. I called comcast yesterday. Comcast and time warner merged.......shame on them for harrassing customers.
Same thing here - called Direct TV to check availability of bundle package - Next day got 4 calls and have been getting at least 1 call every day since. We have caller ID and let our answer machine pick it up - no one answers and the line goes dead. Same thing happened about 1 year ago after calling Direct TV - Sounds like that maybe the trigger - ya think?
