Got a call from this number today.  They told me that I recently signed up to receive a $500 check and they wanted to reward me for my interest.  I stupidly fell for it and got signed up for 5 magazine subscriptions, gas vouchers, a "diamond" watch, and will be getting charged $68.28/ month for 19 months.  After getting off the phone with them and realizing that they never gave me a company name and spoke their phone number so fast I couldn't write it down.  I tried to call the number back to tell them I was no longer interested and it told me the number was invalid and doesn't exist.  They had my credit card info and all my personal information and nothing occurred to me til I was off the phone.  They did tell me I had 3 days to call them and cancel if I changed my mind.  But without a valid phone number, that's obviously not going to happen.  Now I have to fight with my credit card company to stop this scam or wait til they charge my credit card and hope a phone number and company name is listed.  But by then it will be past the 3 days and I will have to fight them over it.  DO NOT FALL FOR THIS!!!  They spoke so fast and got me so confused I agreed before realizing what I was doing.  PLEASE DO NOT LET YOURSELF GET TALKED INTO THIS EMBARRASSING SCAM!
