Smart watch issues/scam?

I was talked into a smart watch when I got my new phone.  The agent said as long as I paired the watch with my phone I wouldn't be charged the $10 line fee because I would be using the mobile data from the phone.  Upon receiving the watch I found out that that was lie number 1.  However I have 2 saved chats that both agents said the same thing.  When I tried to activate the watch, it wouldn't activate.  So I chatted for help.  The agent couldn't get it to activate either and told me that I would have to wait 10 to 12 days for the higher end team could get it fixed.  Unfortunately, I didn't know that it would take me out of the 14 day return window.  Multiple agents have tried to activate the watch and it doesn't work.  This weekend I drove 1 hour away to an Xfinity store based on the advice of the Xfinity mobile agent on the phone because she said they could activate the watch and I could return it to them.  Lie number 2!  The employee couldn't even get the watch to activate and said since its past the 14 days they couldn't take it back.  He told me the phone agent lied.  I then had a video chat and was told by that guy that he was starting a ticket to be able to process a shipping label and within 48 hours I would be emailed a label.  Today I received word that that ticket is closed due to it being past the return window.  So I called...spoke to a lady that told me the higher up team is working on it and I would receive a call back with in the next couple hours...4 hours later here I am.  I need help!  I am fed up.  What should I do now??
