According to my Call Control App, this number had 5 spam reports. On Mr, Number, it  has at least 2 pages of spam reports where no one said anything. I picked up the phone and it was so loud, that he probably couldn't hear me. It sounded like a call center. It could've been someone asking whether the caller wanted to further their education or an IRS threatening call that the caller owed money. http://mrnumber.com/1-520-353-4155/complaints
