This number keeps calling and doesn't leave a voicemail. I tried to call the number back but it rings busy

I was wondering if anyone knew what sweepstakes they called from?

it  just showes me the number

Has called me 3 times and asks for different people.

They say they are "Mountian Area Communication". Apperently, we've won shopping sprees and magazines. They said they got the numbers from the credit card compaies as well.

They will ask for your bank info, credit card number, and are willing to use Paypal as well.

I called my CC (Visa), and my bank, and both said they never gave any information out.

They also call from many different numbers.
