Business ProfileforFlea Free Food Supplement

I was using the Flea Free Food Supplements on my dogs for over 6 months. I had spent over $2000 total on products. The product stopped working after my last order of $724.40. After I doubled what my dogs were getting in their food I also started to add it to their water at double the recommended dose, I did that for a week and I was still pulling fleas and ticks off my dogs. I reach out to the owner to see if there was any tips or tricks. He placed blame on me, my grooming business, the trees in my yard than tried to upsell me on the shampoo and insect spray. He told me my dogs built an immunity to the product, pull them off for 3 days than put them back on to reset it. So I did, it didn't work. I got sick so I decided I wasn't going to worry about it right away. Earlier this week people have also been reporting problems with the product not working all over the US and in another country so I reached back out to Chris for a refund because he has a 100% satisfaction guarantee. He told me no, than made up a policy that I had to return the product before I recieved a refund so he can analyze it. He admitted to the product being a bad batch but still refuses to refund my last purchase. All I want his a refund of my last purchase and I will mail back all of his product to him. I have caught him in several lies so I cannot trust that he will give me my refund once he receives the bad product. He has also told me and others he would send prepaid labels for the products than ignores them when they ask for the labels.
