Why is it so difficult?

I have been trying to switch from Verizon to Xfinity Mobile for a week now. Over the past week, I have been on chat with 8 different people, talked in store, on the phone with 4 different people for a total of 2 hours. I am trying to trade in 2 phones, purchase 2 phones, and set them up on an unlimited plan. I have been told that tickets have been made, which then they are closed without any resolution or even progress. I have been told I haven't been a customer long enough, when I have been using Comcast/Xfinity internet for the past 20 years. I was told I can't purchase 2 devices, as I was only approved for $2,000, because my credit score probably wasn't high enough (it is an 832). The cost to switch from Verizon to Xfinity Mobile isn't actually a savings for me. It is about the exact same. I wanted to give it a chance, but if it is this much of a pain to even try to get signed up.... what is it going to be like getting help as a customer.
