We get calls from this number daily, sometimes twice a day. They never leave a message. One time I was caught off guard when they called and answered, they wanted me to do a survey. Just got another call from them this morning.

hank you for the information. I did the survey yesterday and they said they would call if we won something.I did not answer the phone the next time. No message was left. Thanks!

Yes, we have.  They are trying to sell air purifiers.  They tell you that you have won a prize and they want to deliver it to you.
