Yep, repeated calls to my cell, they leave no message, and when I call back the message says: "Thank you for calling Comcast. This call may be monitored or recorded for quality purposes. Please hold for next available agent. (brief pause) We are experiencing technical difficulties. Please try your call again." Of course, then they hang up.
I just called comcast and asked them to put me on the do not call list. Was put on hold for a minute or so and she came back to say it was taken care of. Because of previous comments I expect to get more calls but I just drop them in my VM. I have unlimited VM and texts but I never get any messages. It's annoying for sure!
I have received two missed phone calls on my cell from a number that's displayed as 386-944-6100. I redialed the number, and the voicemail picked up, "Thank you for calling Comcast", followed by a, "our call center is closed. Please call back during our normal business hours." I wasn't fooled by that, since Comcast's call center is open 24 hours a day, so I hung up, and I decided to dial the REAL Comcast number. I spoke to a representative, and sure enough, she told me that whoever called me was NOT from Comcast, and that there is no reason why I should be receiving any phone calls from the company since I'm not past due on any payments or have any unusual activity.
Rule of thumb, any phone number that is contrary to the one printed on your Comcast bill is FAKE. Chances are, these people are trying to scam honest customers of Comcast, and it's a shame that the world has individuals out there that try to make a company look bad because they can't get real jobs. These people are ten times worse than the bums out on the streets, and the IRS and the police are going to be very interested in their fake activities.
