Hello Crystalbank,
I am so terribly sorry for your loss, what a complete waste of life for the saving of a few pence.
Unfortuneately you will only be able to take them to Court through the small claims court. All very long winded and you will not be able to claim your legel fees back unless the original costs was over £5000.00.
I am in the same position, I purchased a filly in October, advertised as being regularly wormed etc.
the 1st night I spotted round worms and promptly treated her, it has taken three months to get her worm levels down, they were coming out of her in balls of white worms, very little muck, just worms, day after day, it went on for weeks. With persistance and a great deal of help form the vet, I think we have resolved the issue, however I am sure it has had an effect on her long term health.
The filly was sold without her passport, I was told it would follow shortly with her AMHA paperwork. All a pack of lies from start to finish. I have had to source her passport and pay for her Sire and Dam's AMHA transfer of ownership in order to receive her AMHA temportary registration, ok only $75.00, but not the point.
Some breeders should be taken off Breed societys books and be prevented from registering future foals.
If you would like to chat, call me.
