Xfinity does not consider customers and or want business.

I have missed 3 days of work because I have been scheduled to have a home security installation, the first time I was confirmed that same day they would come, I waited and no one came then they said it was because a service needed to be canceled to start a new one. No one called and told us anything once we did that they scheduled us for another day. I missed another day of work I was scheduled between 8:00 AM and 10:00 AM it was 11 I had been in contact with the chat so I had written proof. I was told to continue to wait for the tech would show up it was 3:00 PM I contacted them again they promised to make me a priority and someone would be there between 4:00 PM and 7:00 PM I kept waiting and no one showed up when I see they rescheduled me for that following Tuesday 02/20/2024. Today is Tuesday 20th of February 2024 it is 11:18 AM I check to see my tech arrival time and it says between 8:00 AM - and 10:00 AM I asked to speak to a rep and now they tell me it was rescheduled for tomorrow 02/21/2024 because they "do not have an installation tech available to work today" When they were going to inform me of this? I do not know. So now it is 3 days of work I missed and I guess I have to try my luck tomorrow to see if Xfinity has the decency to come install my home security. They act like Its a free service and that I am being a burden for no reason but I'm paying for a service. If this doesn't get resolved I'm just going to have to switch providers to somewhere they want my business.
