Who called from 7792014191

Received a call from the above telephone number earlier today. Unable to navigate my telephone system's auto attendant. No message was left.

MTC clearly has no idea how a telephone works.

The Instituto La Salle Florida is an Argentine private school founded in 1934 and located in Florida, Vicente López Partido, Buenos Aires Province.

Called, did not leave message but did not hang up, either.  We are registered Do Not Call.

779-201-4191 is a "spoofed" number, which means that whoever called you "tricked" your caller ID to display an incorrect phone number.  QVD on ID - "Life's Giving Moments"
