866-375-9723

this # calls 5=8 times a day with no one on the other end. but they will keep calling. this drives me crazy. how can i get this number blocked from my personnal home number which is suppose to be unlisted.

Same deal as Jenny - this number is calling non-stop and always hangs up. My number is unlisted as well. We have also posted our number to the national do not call list. I would like to block further calls from this folks.

We receive calls from this number several times a day every single day.  I have stopped answering it because I have called ID which only gives me the number. I am on the National and state NO Call lists but that obviously is of no help. I don't understand with as many complaints that I have found online regarding this particular number that nothing has been done to stop it.  In dialing the number myself I get a recorded response from a Teller Response Center which is conducting surveys for Comcast.  I left my name and number and asked to be removed from their call list.

This number has called me every day for a month. I am on the do not call list which is obviously a sham, otherwise the people behind this number would have been fined millions by now.

What is this number 866-375-9723?? They call 4 or 5 times a week and when I answer the call no one is on the other end.

That # calls alot!!! we pick it up and a couple seconds i get the same darn recording for some credit card scam! over and over!!!!!

I repeatedly get calls from 866-375-9723.  No is there when I answer.  Please help stop these calls.

Havent received many calls as yet.... Call back suggests its a survey company for Comcast. Probably offering some promotions and checking customer satisfaction.

Calls anytime of day, laeves NO message. Do Not Call list doesn't apply to survey companies.

Apparently this is a telemarketing company used by COMCAST to get you to sign up for additional services. They are relentless!

we get calls like this to renew Sears service contracts, it might be this number.

this is Comcast Cable calling with account promotions

I've been recieving hang ups from this # for almost a year. This # even called and kept my line open after they "hung up".

I FINALLY answered this number after they called me a ridiculous amount of times throughout the day. It is a customer service number through Comcast. Hopefully now they will go away!!

They call every day. I'm unlisted and on the do not call lists. I want it to stop. They shouldn't be allowed to do this.

Same crap here in my office...every day, every evening, this number shows up on my phone. Finally, today, when I answer with my professional greeting, a young lady says, 'Oh, is this a business? I'm sorry to have bothered you.' She then hangs up.

My office number is ALSO on a no-call list. How do they get away with this?

Those guys call my house 5 times a day how can i block them

Every day at 5:40 PM this number calls my phone.  They do not leave a message and there is never anyone there.

This Toll Free number is Telastar that does surveys for Comcast.  The only way to stop it from calling you is to call comcast and have them remove your number from the data base they use.

Got several Calls.

Said they were from Comcast.  I told them to not call.
