Siesta Carmen Polycarbonate Patio Dining Chair - Set of 4

I ordered a set of chairs and they were described as one color scheme (black %26 blue) and when they got delivered they were white and black. These chairs are for a restaurant, our current chairs have black bottoms and amber colored backs, the ones they sent were white bottoms with black backs (basically opposite). I tried contacting Walmart who then referred me to contact the seller "UnbeatableDeals" to get a refund. I contacted them and they said that I would need to pay the return shipping and to rewrap in the original packing. I explained to them that the item was incorrectly described online so why would the customer be expected to pay for the return shipping, they didn't answer. I contacted customer service and again was no help and they couldn't come up with any solution because I didn't have the "original packing". I also noticed they updated the descrption to the correct color chairs NOW but still have the incorrect photos. I will be much more cautious on what I purchase on Walmart.com and never purchase from "UnbeatableSales"
