Most phone companies, U.S Cellular for one, are not alowed to supeona your phone records. I don't care if you get 100 hang up calls a day. If you call them and tell them you are getting hang up calls from a restricted.pvt. number, they will tell you that they can't do ANYTHING due to privacy laws. So I contacted the local police and they will tell you not to anwser the phone, or have it blocked.but they are NOT going to supeona cell records for annoyance calls. They have more important things like traffic arrests, drug arrests, etc. They wont go through the troubles of prepaid or spoof cards either. MOST police departments wont.To much time and effort.
