If you gave them a credit/debit card number, call the bank/card company immediately & dispute the charges unless you want to be billed every month for $29.95.  No company name = probable scam.

I got some scam company saying I won a $100 gift card from WalMart and if I gave them my credit card number they would bill me a $2.95 handling fee. Then proceeded to say I just bought a $29.95 per month plan of savings certificates from them. The caller would not give the company name except that it was a pomotional company.
