Called 6/22/15 at 12:13 pm PDT. Caller ID showed "Riverside CA". Previously called on 6/4/15 since which time call number has been blocked. My phone answered by Sentry robo call blocker which advises calling party that we do not accept calls from telemarketers, to remove our number from "their call list' (legal requirement and obviously not done) or press 0 to leave a message. No message left. Call Hunter reverse look-up shows this number as belonging to Central Office, Woodcrest CA, Charter Fiberlink CA-CCO. Am on Federal DNC list plus have an unlisted number.
Looks like they are using this number again. This number showed up on my caller ID calling my home phone at 11:43 AM 4/6/2016 with Out of area instead of a name listed. This call IS in my area. Definite sign of a scammer! Caller did not leave a message.
