Nugenix - Terrible Customer Service
I called Nugenix to cancel the auto-ship plan. The customer service rep "Gonzaga" attempted to manipulate my answers. He then insulted me by sarcastically saying that it's smarter to pay more for Nugenix. (I have no intention to use that useless product ever again.)
I also felt like the phone service's "please wait" recording is designed to disarm potential service cancellations. It always sounds like a customer service rep is about to pick-up so that when one finally does, you're not expecting it and they can ambush you with their unethical business practices.
From what I've read, there's nothing special in their "miracle" formula.
