Had run out of product before my subscription date, so I ordered more. When the subscription came due, I declined the shipping order and spoke with someone about it. Somewhere the wires got crossed and I got a notification that the product had been shipped and my card charged. Called immediately and things were taken care of. Only reason for four stars instead of five was that they need to have better communication between departments. I did receive an extra subscription free which more than makes up for the communication error.
