Priority One Clearing unwanted, unsolicited magazines Clearwater Florida

Today I received 2 magazines in my mailbox that I did not order.  I called the number inside the mag and they said it was ordered by a third party and I would have to call them.  I did so and got a recording telling me their business hours and saying if it was during (it was) they were on another call and would call me back.  Of course, that has not happened and I am afraid I have been scammed.  I cannot find anywhere that I have been billed, as yet, so worry where they are going to charge me.  This is so frustrating.
