Support issue along with very inadequate customer service.

I have been having an issue with my line to where I get an, "Invalid US Number" error on multiple authentication sources. I am also unable to actually receive any kind of 2 factor authentication. This is very frustrating to deal with. On top of that, I sat on the phone for 42 minutes in-between hold sessions with 2 different support agents. This is ridiculous. I did not get my issue resolved and after getting transferred with no communication between the transfers, I was then hung up on. I am paying for a service and I expect adequate customer service as well as a working mobile line.

I am following up here as my issue is still unresolved. It is still saying the number is an Invalid US number.

I can’t believe what happen to me! 35 years with comcast and this is what they tell me. Talking to customer support and escalated it to a supervisor they said the wrong thing to me! First they tell me I need to change My plan then they tell me I need to get rid of my land line. Then they tell me I will not lose any of my spot channels.  Ok then since they wanted to change me over $40 for the land line I agreed to that but we also agreed that I would not lose any of my sport channels. 2 days later guess what I did lose one of my  only channel I watch!  They said I can get it but it will cost you for that channel $30 more a month. Oh they pretty much said take it or leave it. I am telling everybody I know about this customer service! I just want to say if the customer service rep couldn’t do anything then I blame the supervisor that was very unconcern. If the supervisor couldn’t do anything then people need to know what Comcast is alll about and how they treat senior citizens.
