Don't answer numbers you don't recognize!! Google the ones you don't recognize and most times you will find out it was someone phishing for information and you shouldn't answer or they will then know your number is a live number and will continue to call back. If I don't know them AND they don't leave a message, they get googled and then added to my "SPAM DON'T ANSWER" number list with a silent ringtone.
I guess, if the company is legit, the phone number they called you on is how they';d let you know if you won, but I would NEVER give them my personal information. Probably a scam.
This is a scam. Trying to sell you on free tickets for a cruise. Press 3 when you hear the message to be taken off their list. And then add your phone # to the national do not call registry. You can report them from there if they continue to call.
