Problem with More.com

[KoLoSo]

Great deals at More.com! First time customers buy $10 worth of drugstore products, get a $25 giftcertificate to the store of your choice with free shipping over $20! More.com

I found this deal at two different sites and used it but when I checked out my credit card was charged with the $13 of stuff I got PLUS the $25 for the CG. I immediately notified them...they said just to deny delivery and they will debit the account within two months, now I can do that but....I want the stuff and they had advertised the deal, now they say it should have been me buying $25 of merchandise to get the GC. They do have that as a deal too. I also sent them a hyperlink to their page that says $10 of merchandise. I'm really irritated. Does anyone have a suggestion ?
