Transpet Couriers

I bought and paid for a tea cup piglet from a breeder in upington. they arranged for the transpet courier service to transport the piglet to edenvale. i paid the fee that the breeder stated . whenb the pig was delivered to the courier company they said i had to pay r 3825 to cover the cost of the electronic crate. they said that most of this would be refunded. the next day they sent another email to say they cant deliver the piglet because insurance had not been paid and another r3100 was required. they are now holding the piglet to randsom saying they will keep the piglet until i pay the further amount. this is a major and dont be drawn into it.
