yahoo - dance, dance revolution

I went to Yahoo, then dance, dance revolution and ordered what the ad said was dance, dance revolution

I wrapped it as a Christmas gift to our grandsons - when they unwrapped they knew (I didn't) that it was NOT dance , dance, revolution

I was told to return it , but need info from the box they mailed it in, which I do not have

How can they get away with an ad that is altogether not true? What else can I do?
