Query: Defective product

I purchased the leash and harness back in Nov 2011. Last week, the metal clasp/hook of the leash that hooks to the harness literally just broke apart to pieces while I was walking my dog. No, I do not have a 100lb dog who likes to drag me around. I have a 22 lb Bichon who is blind. I love the softness of the hemp but cannot trust this product based on my experience. Seemed like a good product based on the positive reviews but I am now noticing that all the negative reviews are about this exact same issue. Clearly a defective batch in the mix or time will tell. I want a refund or at least a replacement.
