UPX courier Scammed by Fake Puppy courier Nationwide

 I found an ad that was selling yorki puppies that have been registered and have had their shots. To me that was what I was looking for. The lady said that she would send them to me that I just had to pay for their travel ticket and I was fine with that. The puppies were dropped off at the airport and I would be contacted soon with the flight number and tracking number. When I was contacted I was asked for $657 for the travel crate for the 2 yorkies. The airport did not contact me it was UPX courier. Only one number would call me and I was only given one number to contact. After I made a $300 payment I was told my puppies would be here at 9am. Nothing. I keep getting emails that they want more money but stopped replying to them. They ask for $600 more $300 more or just give me excuses why I have to pay.
