Priority One Clearing Parenting Magazine I received unsolicited Parenting Magazine subscriptions. Internet

I began receiving unsolicited Parenting Magazine subscriptions.  I googled and called Parenting Magazine subscription department.  I gave my address and the customer service rep cancelled my subscription and said the last magazine will be in two months.  I asked her Who sent the subscription and she said Priority One Clearing and I asked if she had a phone number which she gave: 727-443-2200.  I called and got no live person and hung up.   When I googled Parenting Magazine for their phone number I could see that other people received the unsolicted subscriptions and then would get bills for them.    I also read that some people shopped in certain stores and then started receiving unsolicited magazines.  There should be a law preventing such overall waste... A huge waste of my time,  a waste of paper (magazine I will not read), a waste of resources.
