Who called from 6782454500

Left a message - an attempt to extort money using false claims.  Do not answer, do not call them back.

A machine repeated the original number and ask me to call back. That was it. But the odd thing was the machine/robotic voice. Strange

They called me three times yesterday,left barely audible voicemail and just repeated number twice.

Find out please who is behind these robotic calls.

In a word - scammers.
