Executive Support Needed

Xfinity mobile (via in person support at the store, as well as telephone support) have been unable to activate a smartwatch (with cellular connection) - over 12 hours of support so far, way too much!  There's nothing left to do except return it, however, I'm told it cannot be returned without activating it first, but it can't be activated (I have no idea why)... so we go in circles. I just want to have a watch with cellular service and pay Xfinity Mobile per the advertised plans. Please get me to the right people to make this right.
