Who called from 3237438543

Called my cell phone.  No message.  Don't know anyone in that area code.  Scam?  Ya think?

Called my cell phone twice in a row. Left no message. Los Angeles, CA.

Called my cell, but left no message.  I've just blocked the number based on the notes here

Call my cell phone and my work number.....wonder how they got both.  Didn't answer my cell but answer my work line.  It was a scam saying I won a free all expense paid trip I just had to answer a few questions.  Only person I can recall giving both my numbers to was Carnival Cruise lines.....my guess is they sell our info?
