Just got a call from this number, but I do not answer calls from numbers I do not know. Whoever it was did not leave a message on my voicemail. I immediately searched this number on the internet and discovered a lot of reports indicating this number is a scam. I blocked this number.

Just received a call from this number. Girl tried to say she was having problems with her headset and then wouldn't stop talking about me getting to stay at a resort for free because of my recent stay at their hotel. I hung up and blocked number.

I don't usually answer for numbers that I don't know, but I was expecting a call from a new doctor's office, so I aswered to these crooks. The voice on the other end was a recording, trying to give the illusion that it was a live person...

It's definitely some form of scam. It said I had won a free hotel stay for my recent stay... I haven't stayed in a hotel, at least not one that I paid for, in 6 years.

I agree with Cal Gal response above:
Didn't answer unfamiliar number. No msg left. Assume it's a crook. Now blocked

No message. Hung up on the machine.
