Hearst Corporation - Invoice
Invoice for magazine not ordered

I received an Invoice in the mail from this Company thanking me for my order! And welcoming me to Popular Mechanics magazine!!! And my first order should be arriving soon! I did not order this magazine which I don't even read, and it says my payment of $17 is due upon receipt. There's no contact phone number. Only an address in Harlan Iowa, with a return envelope to an address in Markham, Ontario. I"m sending the invoice back to them. I've looked for a phone number on the internet and have not found one.
