I've been getting multiple calls a day from this number and its sister lines, -2121 and -2120. CID just says Philadelphia PA and they NEVER leave a message. Been calling for more than a week. I tried to call all 3 numbers back and get the same operator recording: We're sorry, your call cannot be completed at this time. Please try your call again later. I get the recording every time no matter what time I try to call.
