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

same number called me about lowering my credit card rate. ?Said his name was Alex and I didn't catch the name of the company, not to sound racist, but the only reason why I couldn't make it out was because his acsent was so heavy and there were at least a dozen other people making the same phone call in the background

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

Just got a call from (647) 288-1289 saying they were calling from Mastercard to lower my interestrate. I asked who they were looking for and they gave me Mr or Mrs Jenkins. I said this is the wrong number and nobody by this name lives here. They said who am I speaking to? I told them you have the wrong number and dont call here again.

i picked up my phone and it said to press 9 so I did then this indian man came on the phone with a lot of background noise and I said I couldn't hear him...then some of his mumbling...then i repeated myself and I could hear some clicking on a keyboard and alot of background noise then he hung up on me!
