I got a warning from google mail telling me i need to verify my account by giving them my phone number i think I got hacked please help.

I got a text from Google with a verification code that I never asked for.

I got a text msg from a fake Craigslist phone secure site (this is not Craig's List but made to look like CL)  I entered my phone number in response to a CL listing for a free TV.  Ha ha, I got fooled.  They then ask you to enter the secret number and They will call you back with the address.  It's a SCAM.  The text message came from 323-335-5801.

What happened next?  I just went through this same thing.  Did you notice any charges or anything?
