Their customer service is non existent and one of the people answering the phone does not seem to understand english well. I have paid for 3 months and have had 2 shipments yet they are holding my 3rd free shipment hostage until I pay for the 4th month. I have had to call customer service multiple times for mess ups. Stay very far away.
Edit: Do not believe their faux concern below, they are garbage.
We are sorry that you are dissatisfied. We will work hard to earn your trust back.
