Why?

First, Why am I paying for 1000Mbps internet service and only am getting 100Mbps?  If you ordered a 10 inch sandwich and only got 1 inch, then would you be comfortable paying full price?

Second, Why am I on the phone with the phone technician for over 90 minutes to have another one call me 4 hours later to repeat the same steps?

Third, Why do I get in less than 24 hours 4 phone calls and 7 text messages for me to confirm this appointment?  Does Xfinity believe their service call technician's time is more valuable than their customers?  How many times do I need to say yes?

Fourth, Why do I get a call after 12 confirmations that Xfinity does not have the part and need to reschedule?  Even with an appointment the next morning.  So when I asked the customer service representative, the answer was she didn't know and it wasn't her job.  Why call me to schedule an appointment if you don't even know if you  have the parts?

Sigh, what will Xfinity do to make this right?
