A lady called me from this number, saying she is representing Helping Hands Association, doing promotions on travel hotels. She mentioned 4 days and 3 nights for free promotions on a hotel either to Orlando or Gutensburg in TN. She asked whether I was over 25 years old, I said yes. And she asked whether I do have a credit card, I said yes. Afterwards, she put me on hold to talk to a "senior officer". I hung off during the process because I became suspicious. But I already said "yes" to the above two questions. I googled online and found that it might be a scam.
