I signed for what I thought was just a trial supply of Instaflex for $5. In doing so, I inadvertently signed up for an automatic monthly $74.98 shipment.
Misleading perhaps, but it's my own fault for not paying attention to the order information.
After I noticed the $74.98 charge to my Visa, I called Instaflex. I was given courteous treatment and an RMA number to use in returning the unopened package.
I received the package and sent it back along with a delivery confirmation form. Instaflex credited my Visa account for the $74.98 within a week.
