Got a call from this number around 10 am est today. They got my number from an android app I installed. Always check permissions of apps being installed. If it says "Read phone status and ID" they can get your number.
This is about the 5th or 6th call from these clowns. Blocked. I have no doubt they will rotate thier phone numbers and be calling again. Also filed a complain with the national do not call registry, lol... what a joke.
