Poor customer support trying to activate internet

For three weeks i have been trying to get my internet service activated. The first time i called the customer support number I was told a tech was on the way. On the day of i double checked with the app and was told i had no set appointments. 2nd time i set it through the app and was given a date and time through email and on the day of, my appointment was cancelled without prior notice and i didnt even receive a text or email. I set another appointment and was told i would have to pay a $100 technician fee on top of $60 monthly service bill for a modem i haven't yet got activated. I was on the brink of just cancelling my service but i spoke to the loyalty division i set another appointment and was told the $100 fee would be waived but now the rescheduled appointment i set isnt showing up on the app and im still receiving notifications that a tech is arriving on a day i wont be home. This is really unprofessional and an annoying way to treat a customer who is willing to pay for a service he sees value in. Xfinity is not the only service provider for my neighborhood just the only one im comfortable with.
