I would be surprised if this goes anywhere meaningful. Those were marketing promises, not contract terms. I noticed the promotion ended just over 2 years before the price hike, indicating that everyone had completed their contract. Once the contract is over, either side can walk away, or renegotiate terms.
Marketing promises effectively constitute a binding unilateral offer, for the purposes of contract law. When a customer signs up, you also have acceptance, consideration, and intention, thus forming a valid contract. Carlill v Carbolic Smoke Ball Company is the classic case in English contract law; the principles are basically the same in the US.
