Why is it so difficult to change or add services?

@XfinityEmilyB​ - I think the point of my post was missed.......

Where exactly does one go to manage the services on their account (Add, Remove, Change) without being met with the "Sorry, please call us"?   Without and I'll quote from my post "I do not want to call, I do not want to chat, I do not want an email.  I just want to utilize this wild thing called the internet like many other companies allow us as consumers to do."

Or is this just a part of how Comcast /XFinity does business by not providing this access and information to its customers.   Kind of like myself, who has been a customer since 1977.  

It seems like what I'm  asking is a pretty reasonable request and almost every other company out there allows for this interaction.  Doesn't sit well and seems like a pretty shady business practice.

I definitely understand where you're coming from, @user_1046d3 and I apologize that the website is not giving you the ability to put together a plan. This could happen for many reasons but the most common that I see is when your current package is grandfathered and we're unable to add or change service without changing the whole promotion. I'm happy to take a look from my end and explore options with you if you're able to send me a Direct Message. 

@XfinityEmilyB​ - Doesn't see like that that option to direct message works for me either.......

I really appreciate you giving that a try @user_1046d3. Do you get the error symbol after clicking on the pen and paper icon on that screen? 

@XfinityEmilyB​ -

Link is not active.  Hovering gives the symbol I posted.  This just adds even more to the frustration at this point.  I wanted to get a few simple answers without having to call or sit in a chat.  The chat I was in prior to my initial post here went on for more than 30 mins for a few simple questions.
