Worst Customer Service Experience/ Inconvenience with False Advertising

My name is Serena, I have been a diamond member with Xfinity for over 4 years. 

2 days ago I was pitched an offer from an Xfinity agent who advised that I was eligible to receive a free smart watch valued at $300 but all I would need to pay is the monthly service fee of $10+taxes and also that with this watch, I can pair this with my phone/number that I already have with Xfinity. Based on the information provided, I decided to accept the offer and I received the watch the following day.

Once I attempted to pair phone with the watch, I kept getting an error and I called the service number provided on was connected to an agent that advised she saw the issue, the issue was that it was not activated and she opted to activate this. This did not resolve the issue and I requested to speak with a supervisor. The supervisor advised this was an error in how the agent processed the order as a stand alone and the watch had a separate number and could not be paired with my phone number I already had.

 have spoken to 4 agents and 3 supervisors between yesterday and today and I am being given several different answers and twice I was transferred and it was just dead air. I have been on this last call for over 3hrs and still no resolve. They advise if they remove the number I will lose the promo and have to pay for the watch or I may need to return it and have them reissues this.

Xfinity is by far the worst company I have ever experienced in my life and their services is one of the worst. They do not train their agents and their supervisors aren’t much different, they lack empathy, they do not listen to understand and they provide false information that has inconvenienced me as a customer and this is absolutely unacceptable. 

I need this to be resolved without suffering the penalty for their mistakes.
