promotional prices not honored

About a month ago (July 3), I called to discuss better pricing and was transferred to your Customer Loyalty team. The representative I spoke with offered me free internet for 12 months if I signed up for Xfinity Mobile. He explicitly stated multiple times that both internet and mobile would be free for that entire 12-month period.

Trusting that agreement, I signed up. However, it's now been less than a month, and I've already been charged for mobile and internet services twice each. There was no mention of charges, conditions, or fine print at the time of the call - quite the opposite. I was reassured repeatedly that I wouldn't pay anything during the promotional period.

I've tried to resolve this through customer service but haven't gotten anywhere. I'm asking for:

1. A review of the original call with the Loyalty rep.
2. A reversal of the incorrect charges.
3. Confirmation that the promised 12-month free period is still in place.

I'd really prefer to resolve this directly rather than escalate to the FCC or BBB, but I'd appreciate a quick response and correction.

Thanks.
