Worst Internet company ever

I booked two weeks in advance to prevent the situation for some reason my address is not being shown into their system, and the technician lied twice on the scheduled day stating that I was not home when I had been home all day never received a phone. Call a text message. Nothing to notify me. I work from home and my Internet services are just as important as me obtaining my job. 
I am 100% on satisfied with the services provided every single person that supposedly assisted me failed me. it’s so hard to get in contact with anyone. and now they’re telling me that I have to reschedule for the third time. the service technician lied and said that I was not home, but I never received one single phone call to notify that he was on his way so that I could help assist with better details and descriptions of the front gate. I hate this company so much and never will I ever trust Xfinity.
