240-556-9966

An automated message in Spanish. Called at 5:44 PM Pacific.

I didn't take the call.  No message left.  I called back and got a recording saying that they would remove me from their call list if I pressed #1 on my phone, so I did.  Don't know what will happen.  I have received 2 spanish advert text messages recently, directing me to a website.  Don't know if related.  Here's information from whitepages reverse lookup:
Type: Land Line
Provider: Paetec Communications
Location: Washington 236, MD
Unpublished.

paetec.com--they provide communication services.
Maybe they own the number that someone else calls through, for whatever reason that person calls.

Got a call from 240.556.9966 (washington) around 10nish this moring.  This is the first time that I got a call from this number on my private cell phone..but I’ve received other marketing calls before and a lot of them are from Florida!!!!

These, unsolicited calls are an annoyance and waste of resources!!!  Use call blocking for this number, besides opting out from their database.

We got a call from 240-556-9966 last evening about 8p.m.  We didn't answer it and the only message left was a very loud shrill noise.  I don't appreciate these calls and wish that they would stop calling my number.

Just received a call from this number..left a voicemail about Dan somebody running for some office in Illinois and is endorsed by the Tribune..srsly? How in the heck do these people get cell phone numbers? Go away.
