"Accessing Your Account" - Can't edit to change my payment options or upgrade my cable service

I am able to login in to Xfinity but I cannot do anything when I am there.  I get a message that they are accessing my account.  I need to update my bill pay as my bank account merged and I have to input my new account number.  There is NO WAY that I can find to actually talk to a human to resolve this.  Also, not sure what an email is going to help since I can't access my email due to this issue.  

XFinity/Comcast if you receive this call me on my cell phone on record. Otherwise I'll never see and won't be able to pay you!
