Who called from 4153635668

These(foreign) people keep calling to offer me a $500 gift card just for verifying that I am a visa or mastercard debit card holder. All I have to do to verify is give them the:
Name as it appears on my card
the account number
the expiration date
and the security code.

haha they obviously think I am stupid!

I received a call this morning on my cell and person spoke in broken english stating that I had won a $100 gift that could be used at Walmart or Target.  They said I was a preferred customer.  All they wanted was a $1.95 processing fee that could be charged to my credit or debit card.  They verified my name, address city and state and zip.  I refused to give them my cc information.  They got rude and hung up.

Definitely a scam.

Got called twice today from 415-363-5668....  Broken english and wanted personal information.. Would not give out and hung up on them... 4 hours later they called back and got sent to VM.

Called me and told me I won a gift card for 100$. Called back the next day four times wanting a credit card number. Don't sender the call it's a scam

EVERY FREAKING DAY these people call me!!  How do I get them to stop?!?!?!?!  I've told them to lose my number, I'm not interested in what they're offering, don't call me again, etc.  They don't stop!!!!
