Business ProfileforHancock Seed Company

I purchased a seed mixture from Hancock that stated on their website would be 5% microclover. I specifically purchased this mix because of that mixture percentage which I needed for the area I would be seeding. When I received the mix, the label showed that it had ****% microclover. I reached out to the company via email and was told "Our blend percentages listed on the website are approximations, and subject to change based on availability.We try to keep our Microclover blend between 3-5%, due to the fact that too much clover will take over the grass in the blend." First of all, I know how much clover I wanted and made the purchase based on that. Second, it wasn't even 3%. It was less than half of what was listed on their website. I asked if I could return it, but they would not allow a return because I had already opened the bag. I asked for them to send me additional microclover seed to bring the mix to the correct percentage and they would not do that either. I could understand if the mixture was slightly short of 5%, but it was less than half of that. If I'd know that was a possibility, I never would have ordered it. I would like a refund (not a store credit) or I would like them to send me additional clover seed at no cost to me since it should have been in the mix already.
