Had Comcast service for two months and during that time we had four or five service techs come out, numerous calls for help, switched out equipment, and a few stops at the local office to no avail. We never had the service we signed a the contract for from day one, so after a couple of months, I stopped service. The only reason we had service that long is because they kept talking me out of it and saying they would fix things. Now, 7mos latter, I am still figuring out what to do because they are strong arming me into paying, which I refuse to do. They have knocked money off, but I am not paying a dime for something I did not get per the contract, which is legally binding as a signed contract.

I would not sign a contract for a car and then when they deliver half a car, go ahead and pay for that half. I would not pay for any of it because it is not what was agreed upon. Now it is with collections and Comcast claims there is not anything they can do about it. They have even used the fact that I stayed with them a couple of months against me when they are the  ones that kept telling me to wait. A lawyer would cost many times mor than what I owe, so Im kind of stuck. Pretty dirty.

We have been a customer with Comcast for years and years. However, we have moved to a new house and it has been a week and a half and Comcast has failed to still set up our internet and cable. We have called the complaint line several times a day and we are given excuses. We have been promised several times that someone will call us back in less than 4 hours, with that never happening. This is so frustrating.

Comcast is the worst cable company that I have every had the displeasure of dealing with. Your customer service is horrible with individuals who cannot speak English clearly at all.  On Saturday, October 24, 2015 I discovered an issue with my "On-Demand" function, I was not able to access this function on any of my three boxes. The error message read, "Failed to contact the On-Demand server. Please call customer service for assistance. Big mistake because customer service was useless. The first call I got a technician that said he would run a signal to all three of my boxes. This took about 30 minutes. He told me I had to wait 30 minutes and then it would work. I specifically told him before hanging up that if it did not work I would be calling back.

He assured me that it would work. Well guess what, it did not work. So here we go with call number 2. I got the same incompetent technician who again tried to run signals throughout my home. This time he admitted he could not do it so I demanded to speak to a supervisor. I was told that a supervisor would have to call me back. Guess what, that supervisor never called me back. So, call number 3 I made to the billing department. Oh but first let me back up, after the second call, that incompetent technician was able to do one thing and that was disrupt the picture and sound that I was getting.  So on my third call, I had to call through your billing department hoping that I would be connected to someone with a little more brains. I was able to get someone to at least get my picture and sound back, but still unable to resolve my On-Demand issue. 

So, call number 4, by this time, I have already filed a complaint with the Better Business Bureau. I demanded to speak with a supervisor and I was not taking no for an answer. I got one who insisted now that I need to make an appointment for a technician to come out to my home. I was not taking time off from work to deal with this and that it was going to be taken care of this weekend, I did not care what Comcast had to do. So, call number 5 I had to call again, because that so-called supervisor I spoke to on call number 4 told me that I would be getting a confirmation call that a technician would be coming on on Sunday, October 25, 2015.  I never got that call which led me to call number 5. That final call I was able to get a confirmation for my appointment. Damage has already been done.

This is a difficult company to get ahold of. Their customer service dept. is the worst. If my balcony was facing the correct direction, I would have dropped Comcast a long time ago for DirectTV or the Dish, anything but this awful Comcast and by the time I am finished, everyone will know how lousy your company is.

Comcast billed me 80.00 because my "signal is too strong", me thinks not. Then the corporate office hit me with 9.50 plus 9.50 because I didn't pay for repairs to a functioning internet to my property.  Not really my fault their signal is "too weak" or "too strong" or not functioning up to my property.

During a recent Comcast upgrade a few months ago in my neighborhood Comcast (or their contractor) left several feet of 1 inch cable sticking up out of the ground in my front yard and along a sidewalk. It is obviously unsightly and possibly dangerous as it is tripping hazard.

I tried contacting Comcast but the service representative didn't seem to know how to direct my complaint. She took the information all the while trying to get me to sign in on my Comcast account which I don't have. I'm not a Comcast customer but was before Comcast took over from Time Warner. The point being that she said they would get in touch with me soon but as of this morning no one has.

I need a working phone number for Comcast fraud department. None of the numbers I have found work.
