The bottom line is this.  This is known as Caller ID spoofing.  Telemarketers will call you disguised with this number and once you pick up - BAM! you're now a target for further telemarketers.  Unfortunately, Republic Services does use this same phone number to legitimately give out service notices as well.  File a complaint with the FCC on this - caller ID spoofing of legitimate businesses and government agencies is only going to get worse. Do a Google search on caller ID spoofing, lots of recent articles.

I basically have no choice but to block this number because they call about once a month.  They called 5 times in the span of a minute this morning and Republic Services verified that there were no legitimate service notices out, plus my garbage and recycling was already picked up.
