I have NO idea what the disgruntled customers are talking about, but, their complaints must come from when the business first started or something. I've had and have nothing but good things to say about the quality of the oils, the SWIFT delivery of the merchandise and the over all condition of everything I've ever received from them. I haven't had to call customer service ONCE, and even if I did, I'd chalk it up to human error and call it a day. I was actually on my way to the site to make another order. I usually spend $50-$100 at a time(I keep burning through citrus oils like CRAZY. I'm just going to have buy them in TUBS from here on out SMH/LOL).
