What is the name of your state (only U.S. law)? Maryland.

I entered a 3 years contract with XO Communication 4.5 years ago. They've been providing T1 service for us for the past 4.5 years. I recently switch to another company who provider better service for a better price. Six month after i canceled my service with XO Communication, I received a bill for $13,800 of early termination fee. Little that I know that in the original contract has a automatic renewal clause. So my original contract was automatically renewed for another 3 years when it expired.

I have a small business. If I have to pay $13,000 I will be put out of business. This is the most unfair practice. I wonder is there anything within the laws that I can do to save my business.
