SCAM!
This number is related to Comcast. They were attempting to sell me a deal similar to one posted on comcast.com, however their terms stated the initial price would increase after 6 months whereas the comcast.com deal stated the price increases after 12 months.  When I asked multiple times regarding having the digital cable box shipped, the phone rep became offensive and would only allow onsite installations; i hung up shortly after.

I have been pestered by this number as well as another Comcast telemarketer 800 983 0950. Both access my voicemail - costing me minutes but leave no message - just static. This is illegal and I filed a complaint with the national Do Not Call .gov agency. I have never even used Comcast.

I called Comcast today and told them about these numbers and they put me on their internal Do Not Call list . The customer service person said it will take 30 days to remove my number from all lists during which time I might receive another call - try another 15 or 20.

I have been getting calls from Comcast for a couple but never a voidemal

just received a call from this number with no message.  if this is comcast then i will be calling to have my name removed from their list, which i thought i already did earlier.  
i appreciate the other posts helping me know who is making the calls.

Got a call from this number, but nobody was there when I picked up.  Immediately called back. "Thank you for calling Comcast. Please hold" followed by an immediate "All our agents are busy. Goodbye."
