not happy with my purchase

Hello - i went to xfinity store to purchase new phone (mine finally died) and was able to purchase one, then of course, they trotted out the insurance, which is $15 a month - egad - that is another $180 per year. Insurance doesn't have to be that much - $15 a month for insurance is quite high for a $649 phone. Next, i was told i have rewards! Of course, my rewards cost me - so there really are no rewards. The reward was $300 for a watch that provides text and voice, and a bunch of other stuff that I don't use because it doesn't fit my lifestyle. I got caught up in the emotion of the purchase and the "gadget" that would be in the my life for the next two years. Well, it turns out, the watch was $350, minus the $300 reward, $50. Okay, i was required to pay state tax on the entire $350 - plus, and no one told  me until i saw it on my phone and questioned it, that there is a $10 fee, per month, for service for the watch. I had a two week window to return the watch, but I vascillated and didn't, which i regret - plus, the transaction was complicated by me not having all of my passwords memorized or written on paper - then the gentleman, began using the f-bomb - not at me, although, was peppered through the conversation. All in all, i'm not happy - I'm out $240 for the service (for the next two years) - because it is a two-year contract, which no one explained to me, or pay someting like $100 to end the contract and keep the watch but no service. I'm starting to wonder if xfinity is having money problems because of all these "rewards" that cost consumers extra hidden fees. Now, they came out with xfi - which is supposed to be the end all for our home and whatever.  on the bright side, we do enjoy xfinity in our home - and yet again, the fees went up for 2025. (oh, and to be fair, the tech reduced our monthly payment so that I could buy the watch) - i just don't want it - and i waited too long to return it
