I have been receiving calls from this number (504-723-5296) for the last 7 days at EXACTLY 10:20 AM each and every day. It's a cell number through Sprint located not too far from where I live, but can't seem to find out the owner (YET...) I'm thinking it's an automated sales call/telemarketer, because the calls come in everyday at EXACTLY the same time. I'm going to be contacting Sprint directly about these calls, as I have the logs to prove it. Each and everytime I answer, I can hear someone breathing, I say "Hello?" and they hang up abruptly.
Typical nuisance call = being reported.
