Globalflightcatchers

I reserve a trip for me and wife, the pruce was very ship for a Delta flight. They offer a cheap fare and then after 2 hours they call me back that the offer its not longer avialable. The catch is they offer a higher cost fair and they cant refund my money back. Finally they told that they will be a charge for cancel a reservation cant never was completed. I call Delta and they told me that fare is not real. Dont make reservation with this guys you cant loose your money. I call to my credit card service provider and the credit card was free due other complains from.this company.
