Return of Apple Watch due to misinformation at retail store

Hello, On 5/28/26 I purchased a new mobile phone at our local Xfinity store in Weymouth, MA. During this transaction the employee offered the free Apple watch promotion and told my wife and me that we could cancel the line after 60 days and keep the watch. We verified several times that we could cancel after 60 days and not be charged.

When we called Xfinity Mobile on 8/6/26 to cancel the line, we were told it was not possible to do that. We were totally misled by the store employee, and from reading other posts on this forum it appears this deceptive practice happens frequently.

The Xfinity rep we spoke to on 8/6/26 (Max) said that we could Fed Ex the watch to your warehouse in Mount Juliet, TN as an "unsolicited return." She mentioned that particular store has fraud issues. Then 14 days after the tracking # shows as delivered to the warehouse we should contact Xfinity Mobile to check on a refund.

My questions today are:

Can Xfinity Mobile provide a Fed Ex label for shipping the watch to TN?

Also, should our data on the watch be deleted?  Watch unpaired from phone?

Thank you for your help.
