Who called from 4126886780

this number calls all of our phones, landline and cell, never leaves a message. Multiple times a day and multiple days.

Number keeps calling my free texting app number sometimes upwards to eight times a day. Cannot receive calls on the app so can only look at the missed calls piling up. -.-

Why can't something be done about these annoying calls.  This caller calls a couple times a day, day in and day out.  Never leaves a message.  The caller ID just says Pittsburgh
