Frustrated with Mobile

We recently moved our service to another mobile provider due to poor customer service. It has been a nightmare trying to get the transfer PIN, which I finally just had to go to a physical store to get help. We have Apple Watches which were associated with our Xfinity mobile account, and it was our understanding they would automatically deactivate when the phone lines were ported to our new carrier. Well, of course it didn’t happen that easily! Why am I not surprised?! Our Apple Watches are still active on our xfinity mobile account, despite multiple attempts to chat in with an agent to get them deactivated and removed from our billing statement. Each time, the agent “confirms” that the watches are deactivated successfully, but of course they are not deactivated and are still showing as active on our account, and are still being billed. Why does Xfinity have to make this so difficult?! I shouldn’t have to make another trip in to a physical store to get this taken care of.
