some girl came to our door selling magazine subscriptions. My husband payed 63.00 in cash for 3years of "Shape" magazine. When I got home I was furious and cxled the subscription by having my husband sign the back of the receipt and sending thru the post office back to Mts Circulation. They sent me a letter and said I need a copy of the cxld check. The receipt says it was paid in cash. How do I get my money back from this scam.........
