got a call 4:23 pm mon. may 5 -mastercard must be reactivated?? it was  a taped message--wanted me to call another number--that no. said press 1 to reactivate your card then press 2 and enter your 16-numbered card code!! i just hung up...it was from canada 780-943-0637--

I received a call at 5:03 a.m. on May 4, 2014 telling my my Debit MasterCard had been suspended and to press "1" to speak to a security representative.  I was half asleep and pressed "1" then got the same message again.  Hung up right away.  Checked with my bank and my mobile phone company to make them aware and note my accounts.  It frustrates me that people spend their time trying to inconvenience the rest of us.

Got call at 6:15 AM on May 4, 2014 (asleep naturally) saying something about debit card.  Probably punched the wrong number to be connected to a department.  Likely a good thing.  Will call our bank DIRECTLY now.  Likely a scam.  

A-holes called my cell phone at 4:35am.  As Mandy and Ty suggest, likely a scam as no legitimate telemarketer would ring at this hour.

Got a call from this number on a Sunday saying that my Mastercard Debit Card had been locked, and to press 1 to be transferred to the security department to unlock it. I don't have a Mastercard, so I hung up. I'd like to figure out how to report this as a scam, though...

Called and I answered.  Recorded message saying my credit card had recently been locked and to dial a number to reach the "security department" to resolve.  My card isn't locked so I figured it was dead beats trying to steal my info and I hung up.
