I've received a phone call from this number on my mobile. I'm italian, the voice was an automatic recorded voice, I did'nt understand very well but she said something about customer service.
Has anybody received a phone call from this number?
I'm curious to know where it was from!

I did, I do not know what it was about. I did not call back, because I was abroad. I do not know how they found out my number, because I gave it to my relatives only.

Yes this is the company called AIR BnB when you do some rservations to get a room on that web-site and this si the customer service number to reach thenm if you got any questions about your billing, it's a legal number! YES!

I have received several calls from this number today. They leave an incomprehensible message, so I don't call back. I am using the airbandb website to find lodging, but didn't think that they would leave messages that were not from the people with which I am communicating.

That is the Airbnb Customer Service department. They were trying reach you to offer assistance or to let you know there was some difficulty with your account or reservation. You gave them your number when you opened your account.
