Channel guide

After calling twice, being on with a rep over 2 hours, not only did rep not fix my problem, she disconnected my phone line.  Did t realize what she did, had to send a tech to my home.  He was great, was able to get someone tokreconnect phone line,  but......my original concern still exists. My channel guide is incorrect on app and xfinity.com.  It seems to be from another area and not my area.  T(e reps on phone, don’t understand and can’t figure it out.   I’m paying a lot of money and I can’t watch tv live from my laptop, ipad, or phone, as the channel listing is not my area.  My TV has no problem.
