I had the same phone call today, but stupidly gave out my card details, only that the card can only be debited if I put money on there.
The only thing is from filling out the entry form they have all my personal details. Is there any advice from anyone of what I should do???? Im worried I will be used in some sought of fraud. PLEASE HELP CONCERNED. Is there anyone I can call

went on website for cruise holiday competition 12mths ago, they called and said i won with radisson hotels and caribbean cruise free holiday and accomodation in fort lauderdale, florida and cruise in bahamas. luxury holiday tax to be paid by winner 998 usa dollars and flights could be arranged with quantas at discount through all seasons travel and paid by winner. 2yrs to use tickets and accomodation deal to funparks etc, downpayment required by credit card on the spot if wish to accept, confirmation emailed immediately. After gave credit details then mentioned radisson had deal with timeshare company and would be required to attend 1 day session in fort lauderdale and florida. Refused offer but given run around and customer service numbers and addresses to reverse agreement to accept offer and stop credit charges. Hoax discovered as number not in service, no reply from writing and found these complaints in support of suspicions. Disputing credit charges with bank and will be refunded hopefully, cancelled cards so they cannot get my money again. Lesson, never, ever, give out credit details to anyone who calls you or by internet/email. Only do it if your approaching them ie. buying stuff on the net and use an accredited secure payment method like paypal or through your own bank website online (b-pay). these scammers are calling internationally now, not just the states as I see going on months ago from this complaint system.

I received the phone call this morning saying I had entered a competition for a trip to the Bahamas and that my entry was accepted (not that I had won) and then went on about where I could go and that it was for 4 people and a few short words about 1 day in the Bahamas, I was suspicious when he asked if I was over 21 and the owner of either a MasterCard or Visa card and waited for the sell line and when "Patrick" said he was putting me through to bookings I hung up. The phone rang several times with number unavailable and I did not answer. My worry is that they had my email address and were then wanting my home address which I didn't give. Patrick was very cheesy in his sell commenting about me being single etc. Please don't get caught up in the "I won" feeling and think about the I might be going for a ride and its not a holiday feeling! Thank You all for your stories as it is these that now make me aware of anything that sounds too good to be true
