Fraud - Selling of Puppies

Best Chris Puppies is a website https://bestchrispuppies.co.za that "sells" various puppies. Once you have made contact with them they are open and communicative. They send photos which could be generic or fake, they are that convincing. A payment of R3500 plus R450 freight charge was paid, once received it was acknowledged and informed the puppy is on its way and will be delivered within 24 hours. Then another email is sent a few hours later from a "shipping" company (using Unitrans Logistics as the front), asking for further payment of a freight box and thermal blanket (prices range from R13-R16k). The additional freight cost was queried via whatsapp and email to which no response was received. The cellphone number has not been switched off and "Chris" is still active on Whatsapp.
