Scam alert

I bought a puppy online from Shiloh Smith Breeders in Kimberly and was contacted by the above company as they were instructed by the breeder to transport the puppy from Kimberly to Port Edward. Dr Larry from the company sent me an email advising me that we have to pay an extra R15750 for the renting of a special cage for the puppy and upon delivery of the puppy R15000 will be refunded to me. I agree to it and paid the requested amount. Shortly thereafter I received another email from Dr Larry requesting an additional payment of R35500 for travel insurance. Upon receipt of this I cancelled the entire transaction and requested Dr Larry to refund me the R15750 that I have already paid. I am unable to get hold of Dr Larry or anyone of the company which let me to believe that this is a scam
