Intervet - Zylkene 450mg Capsules for Large Dogs x 10 Pack

I can't comment on the product. I am sure it is very good. However I never received my order (back in May). I contacted the seller to ask for a refund. He confirmed he would do this. It is now almost October and I am still waiting for my refund. Once again I have contacted the seller and I am awaiting a reply.
