Prank phone calls from 559-515-8713.

These prank callers call from several #'s they all seem to start in 515-559- then varying last 4 digits, not sure what type of router/calling system they would be using, but I doubt they are very sophisticated individuals, so it must not be too complicated. They have called my call center 100's of times. If anyone can figure out who they are and or where they are calling from would love to find out, and could provide plenty of documentations of their calls, and there impediment of our business. Would like to see some sort of action taken against these punks.

These people call calling you via skype which reroutes thought a landline number. I also work in a call center and we also have recieved hundreds of calls from their varying numbers, 559-515-...., 661-...-.... and 0000123456 on caller ID. Note that they can manipulate the caller id. We believe they are likely calling from an international location -preventing law enforcement intervention.

It's a skype number for those who don't pay for online numbers.
