Recourse for services not provided

I paid someone to build a website for me. At the time of the contract the total amount was $400 for a 5 page website, logo, brochure, and blog. She later increased the price of her services ($250) and added on hosting for one year without my knowledge or consent, bringing the project total to $650. She claimed that she sent me an email with the updated price and since I never opposed it she assumed I was okay with it. I refused to pay the extra $250, since I never agreed to a price increase or hosting (which I already had). She had been pushing the final date back for months and when I finally confronted her she advised that I was on her 'unpaid client' list and she was not actively working on my website. Do I have any recourse for either getting my money back or forcing her to finish the website? Thank you. I am located in New Jersey but she is located in Georgia.
