Their refer-a-friend program and customer service is trash. I referred a friend, who made a 3 bottle purchase and I couldn't redeem my free bottle. I tried over and over to resolve my issue through email and speaking to their customer service 3 times. Just kept getting the run-around. They kept giving me codes that don't work, and instructions to "choose a coupon from a drop-down box" that doesn't even exist on the site. It shouldn't be this complicated or cumbersome. They always say we'll have an "expert" call/assist you, but all that is an excuse to get you off the phone. Then you get an automated email the next day from "Jay" who basically tells you the same thing. The last person I spoke to "Alice" pretended she couldn't hear me halfway through the call, "hello, hello, hello, no response. Ending call." And hangs up on me. Who does that? Basically its a scam, because they make it so hard to redeem your free bottle for referring a friend, frustrating you in the process so that you give up trying.
