Caller says "NEXTUC MIGRATIO". Phone rings once and they hang up. Nextuc is a cloud based computing company. No reason they would ever call me, much less so on a Sunday morning. My first guess is that this is some kind of microsoft scammer who spoofed a real computer company to appear legit.
I call back after hours (using *67 to block my number). I hear the following, "hello, and thank you for your call. We're sorry that no one is currently available to speak with you at this time. We are assisting other patrons, away from our desk, or we may be currently closed. If you would like to try again at another time, our offices are open Monday through Friday from 9 AM to 9 PM eastern standard time. Our weekend hours are Saturday 9 AM to 9 PM and Sunday 11 AM to 7 PM. At certain times of the year we may remain open until 11 PM eastern standard time. To speak directly to a customer service representative, please, call back during these times. Your call is very important to us. In order to help us serve you better, we greatly appreciate any feedback you can provide. If you're calling to request that you be placed on our Do-Not-Call list, please, take a moment to leave a detailed message along with your name, complete address and phone number with area code. Thank you very much. Please, leave your message after the tone. When done, hang up or press the pound key."
