Xfinity Mobil could not help me

You do not offer a service to have and additional Apple Watch on my plan. One connected to my phone line and another on my plan and accessible through my phone with its own stand alone line. I have paid my devices off and plan to change to Verizon. My mother has Alzheimer's and I need to be able to track her. My phone call was over and hour I clearly stated what I needed to do and wasn't told it was not possible until I spoke to a supervisor. When I paid my devices off they didn't unlock my phone. So now I have to call for the 3rd time today. This has taken up most of my morning. I am so frustrated with Xfinity Mobil and disappointed. I could have saved money if you gave me credit for my trade in phone but that was also not allowed. Absolutely disgusted with Xfinity Mobil and will be writing a review.
