UPX Courier Che Martin Puppy Scam Cameroon Doula

I found someone selling Siberian Huskies online.  They said they were from Montana.  The dog was advertised at $200.  The person left their phone number and said they would only text, so do not call.  I could tell their English was broken via text, but that didn't alarm me.  They sent me photos of the puppy.  I asked twice for them to send photos of it's parents.  They said they were not there at that time.  They then told me they were headed to a courier service that will be shipping the puppy with registered papers and i should expect delivery tomorrow.  I explained that i didn't know them, and they didn't know me and I was hesitant about sending a check.  They said not to worry i would be sending $300 (notice how it went up $100) to the courier service.  After investigating more about UPX Courier service and this website, THIS IS A HOAX!  Thanks alot W. Africa for ruining my families Christmas.  Sincerely, one pissed off State Police Officer
