Zero logical discussion on the customer service side. When someone places a $550 order for multiple pieces you take care of them, not threaten with ultimatums. Need to take the 30 day guarantee off their web site if they do not plan to stand behind it. Pointed out the product is subpar manufacturing and they offer to send a replacement.. which makes about as much sense as asking your customer to pay shipping to send back a product that was clearly damaged in the manufacturing process. Stay away!
