Registered for free 15 day trial thru a website, after first shipment I called to cancel but they had already charged my credit card. So I called Vapex and was assured I would be deleted from automailing. Today I received another shipment from Sinless Vapors. Who told me to return the merchandise and they would issue a refund. This time I was given a number to display on the outside of the return package, and upon receipt they would issue a refund. How do I stop these people?
