This number is a scam.
Acting like she is a  debt collector and ask you to call a different number which will tell you they are trying to serve you or pay today.

A scammer, bottom feeder, leaving a bogus message from 'Emily Vonn'  saying to call 844-707-1554. Sounds like a script or pre-recording, which it is. Absolute B.S. Zombie debt, pond scum.
