Who called from 7866071985

I called back from a blocked number and got "the number you have dialed is not in service." scammers. Blocking them.

Called my landline.  It only rang twice, did not even get to the voice message.  Just testing the line, the dirty scammers.

Called 1;)) PM March 9. No message. Caller ID says :Miami FL.

Have just about had it! This time the message was a dial tone!  Second such call today; different number, same bs.  Someone will tell them where to get off!

All of these renegade numbers are blocked.  Do you think this is a front for illegal activities and vices?
