Calls from this number can continue for days, several times of the day and night, if answered there is not anyone there, and if you call the number the number is not a valid number, there is no message if you let call go to answering machine. I have had to block the number to keep from getting annoyed by the phone ringing all day and night. There is not any name on the caller ID to determine who this is. Please find out who this is so calls will stop.
They keep calling and saying they are from "Windows" and my computer is being hacked. I told one man earlier today not to call back but I just got another call. It started earlier this week with a call at 12:35 AM and then again at 6:55 AM, 7:30 AM and 8:30 AM. At first it came up as 201-020-1020 and I blocked the numer so now it comes up private caller. Guess I need to block that one too since telling not to call back doesn't work.
