Called me a week ago about Gas Coupons claiming to be from Discover. They already had my credit card number. I never gave it to them. Said they would charge me 1$ for shipping to send me a package. I refused. I received a package anyway from a company called Leisure Time Savings Club. I called Discover and informed them of what happened. They informed me that they had NOT called me and immediately canceled my card and issued a new one with a new number. I received a call again today from EZ1 asking if I'd received the package they sent and that they charged my card $4.95 shipping and handling. I tried to find out where they got my number from, and the person on the phone claimed I gave it to them. An outright lie. Fortunately, they are not able to charge my card since its been canceled.
