Be aware; if you p****off Comcast employees, they will give you this number and tell you later, "oops, so sorry, you must have written down 800 rather than 888.  My bad!"  The 800-634-4434 number is a scam.

It's not Comcast. 18006344434 is assist123

I was online and taking some stupid quiz and to get the answer it asked you to input your cell phone #, and like a dummy I did it, immediately receiving a text message saying that i would be charged $9.99 a month, but reply "STOP" and the texts would end and I would not be charged, but I'm having the number blocked just in case.

Numerous calls, no one there

who'snumber isthis?

I accidentally called this #, and it sent me back a text message asking for a reply of "Y" to begin a $9.99 monthly fee, but did not offer any information about what it was for.  Seems very shady.

Jason   call your phone company and have this number blocked from your bill-it is a third party scammer that is going to charge your phone bill EVERY month $9.99 untill you have it blocked

This number is from Comcast ... you're mis-informed and apparently can't dial the correct number. It's understandable ... 10 digits is a lot to dial, [removed:lang].

Numerous calls, no one there.  Calling back, heard the following; "Please have a paper and pen ready...or for $3.79, you can..."  I then disconnected.
