Like, seriously, who in their right mind thinks any company would give out their manufacturer's names. Why would they let you get stuff from them?
Furthermore, what makes you think they give a hot shit after the items are sold? It's not like you bought any chairs directly from them. You're not their customer, and unless you're about to buy a thousand chairs they're probably not even going to give you the time of day.
And just so we're on the same page- this is just a $50.00 chair. In the outdoor furniture business that's REALLY cheap. It's one of the least expensive chairs we sell.
