You pay for 3 months In advance before you receive the product. Last shipment was in March which was paid for. I canceled in May. They will not refund April and May payments that they took out of my account. They said my account with them has been paid in full. And they will not charge my account anymore. But they owe me for 2 months. (almost 100.00) I DONT GET MY MONEY BACK. DO NOT ORDER FROM THIS COMPANY..
