called, left no message

Auto Trader

- Gave them my CC number! I hope it's legit!

got a missed call from this number, but not sure what its about???? No message( usually something important, a msg is left.)  no clue... any ideas?

How can so many ppl posting their ads on different webs and still got the same call from this number?Chances are this' a fraud.I just got one to~ I have my ads on autotrader, kijiji, and others cant remember.

I got a call from them today as well, it's autotrader looking to renew an ad...
