This company is a joke

On October 7th my Xfinity now service was paused a day early I went through the app and chatted with an agent who said to give it a hour at most and it'll be restored however it was not restored ok so I paid my bill the next day (the 8th) which is my scheduled billing date anyway thinking that was the problem still no service I chat with an agent again still nothing so I get a call back and after troubleshooting for awhile they say I need a technician but won't be out till the 11th I said so I just lose these 4 days ? The agent said no my billing date will be changed ok so it takes until the 11th in the morning it pops back on fast forward to today I check the billing date and it's still the 8th and these ppl keep telling me that I can't change my billing date and that I basically lost 4 days and my son missed school those days (he's on virtual schooling) I'm getting real tired of this company
