auto discount club told me that I won a $100 walmart gift card tampa Florida

on 12/13/13 i received a call from auto discount club stating that i won a $100.00 walmart gift card. was told that there would be a charge of $6.97  once i receive the card. was told to call them once i get it.  Never got it.  called them 2 more times about the card and was told that they do not give out cards. i was told that it will be 3-7 business days which have since passed. no cards received. was charged $4 95 from my acct which was later changed once i found out about this scam. these people deserve severe punishment.
