Disconnection

I went to pay my last bill for my business service and I had over $2,000 in early termination fee. It wasn't by choice that I ended the service as I had to move out of the location I was in and not having a phyiscal office I am unable to use the service. I want to end things the right way with Comcast and pay the bill I owe, but such a huge disconnection fee is not fair. Please help me
