Constant calls from a group of numbers dialed randomly to annoy and waste minutes. They never leave messages.
Also, 779-235-1089, 956-341-0583 786-749-0662,585-326-3258,781-243-8522, 862-208-6066, 504-517-1070.
Another scam. I called and didn't say anything. The automated system instructed me to press 1 to place me on the Do Not Call list three times every 20 seconds before hanging up.
