A Rocklands Estate, Warwick resident has blown the whistle on what she believes is a credit card scam targeting the elderly.

Valerie Simons said she was called at home last week by a man offering her a cruise to the Bahamas for four people for less than $80 in total if she handed over her credit card details.

She refused and after hearing of another person who had received the same call, she contacted The Royal Gazette in order to warn the public at large.

"We have to let people know about this,'' she said. "I think he must be going after the elderly."

Ms Simons said the man, who called himself Anthony Holmes and sounded American, called her home looking for a Mrs. Brown.

She said there was no one of that name there and he replied that he had 75 calls to make before a Christmas Eve deadline and told her that he would offer her the deal instead.

He offered a `Paradise Cruise' with Discovery Cruise Line leaving from either Fort Lauderdale, Orlando or Miami for four people for $79.95 which included airline tickets and hotel accommodation, said Ms Simons, adding that she was also told she would have to take the cruise within three years.

She was also given a number to call (1-800-560-3350) and was informed that the boat had six levels and a capacity of 1,300 people.

The reason given for the cheap price was the September 11 attacks in the US, she was told.

Ms Simons said she met another lady who told her she had received the same phone call and was looking to block her credit cards out of concern that she was being scammed.

Police this week said they were aware of the alleged scam and warned people not to give their credit card details over the telephone.

The Royal Gazette was unable to find Discovery Cruise Line on the internet.

When the newspaper called the 1-800 number, a recorded message said this was the "promotion department' but did not name the company. Due to the "overwhelming response to our recent offer", all operators were busy and it asked callers to leave a name and number and a representative would contact them.

A Police spokesman said the force was aware of two new cases since details of the "offer" were revealed last week.

"We would like to reiterate the advisory not to divulge financial details over the phone to unknown persons" said the spokesman.
