Sorry to hear about your situation. I agree with my colleague--the real issue is not whether you CAN sue but whether it is financially prudent or wise to sue. As my colleague suggested, try to get a refund or dispute the charges with your credit card (or debit card with a Visa or MC logo) company. Good luck.
Answer given for general advice and is not a legal opinion, which would require an analysis of the facts and circumstances as well as the applicable law and regulations.
You can sue in small claims court, but you need to evaluate if it is worth the time and trouble. If you know a lawyer, have them send a certified demand letter indicating what you demand to remedy the situation. If that fails, you could sue. Is it too late to do a chargeback on your credit card (if you paid via credit card?)
