Unfortunately, you have likely been duped and are receiving false promises. There is no direct process for grievance redressal. Mostly because most contracts are verbal and for any legal action it is really a case hearsay.
Awareness is key. Read up on process and procedures. Buy from trusted breeders and ask before you make payments. If you have been on the receiving end of a fraudulent transaction do not punish your puppy for it. Create awareness for others and help them make an informed decision..
If we do not take action and remain unaware, the fraud breeders/ kennels will never give up their malpractice of KCI registered papers.
