credit card scam asking for your credit card #

I also got a strange call but did not answer it.  The number was (647) 288-1289.

got this call today.  i hung up as soon as they asked if it was true that i pay my balance on time.  

creepy.

Tried to get credit card information including expiry dates.Claimed to be a program from MasterCard to lower the interest rate

Had a call today from this number, claiming to be Royalty Travel and I had won a 12 day trip for 4 all expenses paid trip to Cancun and Orlando.  Just have to pay $150 + taxes per person....offer only good today....cannot send info or verify the legitimacy of the company prior to giving out credit card info.  They first guy (east indian very broken english) said it was a promotion with Mastercard/Visa -rewards program for a good credit history.  I challenged this to find out if it was visa or mastercard as I have both....he could not answer my question so I asked for a supervisor....again east indian with broken english who told me I was chosen from the yellow pages....I challenged this based on yellow pages here in Canada is business listings.  I refused to give any personal information even verification of adress since I could not verify the legitimacy of the company.  There is a very basic website with little information.  Eventually they hung up on me knowing I was simply going to continue to ask them questions that they could not answer and I had refused to give any information.  Beware

Received a call but didn't answer. When I call them back its always busy.
