Mislead on phone upgrade costs

I recently switched to Xfinity Mobile And was told that my 3 phone would be eligible for a free upgrade to the new iPhone version that the sales person said would be coming out at the end of Sept or early Oct. Rrcived their you get a new phone email saying it’s “On Us” that has fine print including a device payment plan. 

Called to talk to an agent about being mislead and I was basically told tough luck. When I asked to escalate the call I was told the wait would be 1 hour and they’d tell me the same thing so don’t waste my time. Sitting on hold, waiting to speak with a supervisor or manager before I escalate to the Exec Team and BOD after which I’ll explore certifying a class which I don’t suspect will be difficult. 

After 14 years I guess it’s time to find a new internet and cable provider too. 

Sad and ridiculous.
