Terrible customer service. I needed to cancel my order due to issues I may have with the treatment and medication I currently take. I cancelled within 10 minutes and after 5 emails and several submissions on their contact page, I still haven't received a response.
They're quick enough to take your money, but make it nigh on impossible to cancel or get a refund. There's no phone number, no live chat options. It's done on purpose so they can ship the product out and then deny you a refund under the banner of it being "prescription based" and therefore impossible to sell on after they've shipped the item. You can't even change your card details or close your account without emailing them. What company does that in the 21st century? It's set up that way to scam you.
Stay well clear. Go to a more reputable source that actually values customer service.
