Trouble cancelling package

I bought a travel package for $398 with the understanding that I could cancel within 15 days.  I got an e-mail with the *details* of what was involved (several of which weren't mentioned by the rep who sold it) and decided to cancel the next day.  When I called to cancel, the guy who answered wanted to argue with me about the terms and conditions hung up on me when I insisted he cancel the package.  When I called back, I got the same guy, who wanted to continue to argue.  I noted that the rep had told me I had fifteen days to cancel and asked whether he was going to cancel it or not.  He finally said he canceled it and I would get a refund in 7 - 10 days.  We'll see....
