Cheapoair Cheapoair changes both my travel dates and itinerary Nationwide

I booked three airline tickets on the cheapoair website for a flight from Washington DC to Managua Nicaragua on Spirit Airline from 12/21-12/28 for $665 per ticket, totaling over $2,000 with taxes for my family.  After booking the flight I received a confirmation notice for flights leaving 12/23 and returning on 12/25.  Not only were the dates different but so were the flights.  Upon contacting cheapoair, they told me to contact the airline.  I contacted the airline who referred me back to cheapoair.  I contacted cheapoair a second time and explained again that I booked a flight from 12/21-12/28 but it was changed to 12/23 returning home on Christmas day.  I explained that I did not book these dates, it was 100% not an accident or an error on my part, but was still refused a refund.  I was told that I would need to pay an additional $700 for seats on the original flight that I booked.  After asking to speak with a manager, I sat on hold for 90 minutes to no resolve.  I am demanding a refund because I was charged $2,000 for something I did not request.  Cheapoair should be prosecuted for questionable and illicit business practices.  I will NEVER use this site again and will tell everyone I know who travels about their underhanded business practices.  I would be more than happy to participate in any sort of class action law suit that might be in the works against this company.
