Yes I did when they first started and after taking a $$$ loss, I wrote them off to never try again.
I ordered 3 Whey Iso, they sent me 3 Whey Conc. I then, being like -stupid- wrote them and let them know I was sending it back. I paid for shipping to return the 3 Whey Conc and guess what? Never got anything back at all. Except a standard "our records show your order has been shipped" each time I inquired when I was getting my replacements.
I paid for products. I paid for shipping 3x (to me the first time, to send back, and to me the second time) and I didn't get shit to show for it. If I had kept the Whey Conc, even though it was not what I ordered, at least I would have gotten something for my money.
