sent a book which was not ordered

I received another book in the mail which I did not oirder. I am not even opening it and I am sending it back. It seems the Better Homes and Gardens categories book into series and sends eah book in that series to you even though you return it. I have contacted them previously to cancel all further shipments. But yet again another book arrived. This is thge last time I am being inconvienced by their shady practices. I will return thisd one and from now on any shipments received which were not specifically ordered will not be paid for and will be thrown in the garbage.
