Bests & Worsts Reviews from Amazon

Last night, I ordered O as a gift for my mother. When I went to check out, I saw there was a special price of $5. This morning, I see I was charged FOUR time at the $5 rate. Called customer service, and the rep said there is nothing they can do... can't cancel, and he couldn't even explain to me how it happened. So now, I don't know if I'm getting four copies of the magazine, or if I paid more than full price for the mag. The customer service rep said if I get four copies, I can bundle them up and send them back to Amazon for a refund... but this is a gift. Not really the way I wanted my mom's birthday to go. I'm not sure if this is an Amazon glitch or something from the publisher, but I'm not happy about my experience with O magazine so far.
