I got a call four mornings in a row from this number -all at about 8 am. No message. I called the number back - they said it was Convergent (convergentusa.com) - a debt collector, primarily healthcare collections. They said they had no record of my number and gave me another number to call - 855-343-7885. After being transferred several times they said they have no record of my number. They said they'd put me on there master do not call list. There is also a link on the home page of their website to submit your number if you're getting calls in error. Hopefully the calls will stop now - I have never heard of this company and have no unpaid debts.
I had a missed call, called back and the person who answered said they were looking for a Jorge something something something zalo. My name isn't Jorge so the person apologized and said they would remove my number.
