Unfair early termination fee practices from Comcast Business

I had a 3 yr contract with Comcast Business internet which started on 5/21 and I moved last month. I told them I was planning to move when I got it and they told me I can take it to the new place or if there is no service there, I can cancel it without any consequences.

When I moved, I was given an option of 50% hike on the prices when I requested a transfer. I refused to take it since Comcast was not honoring the original contract with original prices. I assumed the contract is voided since Comcast does not seem to be bound by a contract and can request exorbitant new prices on existing contracts after a move. I called to cancel the service. Then, I was faced with early termination fees which are too high. This means the contract is valid for me but not valid for them. I thought a contract should be binding for both sides. These practices were not clear from the get go. Their contract does not even list the monthly fee for early termination, they refer to another document for it. 

I want to know if there are other people like me. We can go to court.

These practices are not friendly to the customer and very annoying.

I asked to escalate and go to arbitration, but there was nothing from the representative. I ask you to listen to my calls to the customer service and tell me if I was treated fairly.

I request my ETF to be waived.
