Air Pets Services VPI Pet Life Insurance Puppy Scam Colorado Springs, Colorado Internet

My husband and I found a teacup Pomeranian on oodle.com.  I contacted the seller (Jeff Molly,jeffmolly7@gmail.com Colorado Springs, CO) asking the process.  His exact words were just a total of $400.  Once paying the $400 via REloadit cash cards we were contacted by the company from Uship.com.  The first email stated we need to pay $1,225 for carrier and vaccines.  This was weird in itself because the dog was up-to-date on its vaccines.  Between the seller and myself we have paid $1,625.  All was set and a delivery confirmation was received.  Come 5:00 eastern standard time, I received an additional email from another address requesting additional money for pet insurance of $450.  This has gone on for three days with a request for money.  I received a threat to pay or be charged with animal abuse and abandonment.  I feel we have been scammed.  I'm on the verge of a nervous breakdown because I have never witnessed anything like this in my life.
