202-888-9934

I suspect that this is a new number (alternative to 301.328.3949) so as to circumvent blocks to its alias.  Both numbers show "Washington DC" on Caller ID.  "Washington DC" has been calling now for perhaps months, never leaving a message (unless a recorded message is talking over our voice mail greeting).  Yesterday I received five calls that displayed "Washington DC".  We never pick up, even when we're home.  

I keep receiving calls from 202-888-9934,  I never answer and they never leave a message.  Today I answered, and they spent a lot of time fumbling for my name.  I did not tell them and they finally hung up.

202-888-9934 got a call from this number, they talked so low I couldn't hear and told the guy that and he hung up.

They call early in the day, leave no message.  

I just got a call. Some one was just fumbling, I just hung up. I have been getting calls from this number past 2 weeks.

Another terrorist call that our useless government can't stop. The phone companies won't risk profit loss from these calls so all we can do is deprive ourselves of a phone service. Once again the terrorist win while the useless congress sits on their collective ass.   Wake up america you are under attack.

This number has been calling for two weeks.  I never answer orally, I hit TALK amd then immediately hit
OFF on my phone

Making numerous daily-weekly donation calls then after telling them several times to stop calling they make numerous daily-weekly HARASSING Silent Hang up calls using numerous phone numbers.

It's just a company trying to scam.  I think you're exaggerating in your response......PLEASE!!

Called but left no message, CID was AICR, think that's American Institute for Cancer Research. Guess it's a valid charity but their practices seem to be very questionable.

Caller ID comes up as "International"...I never answer calls I don't recognize. If it's legitimate, they can leave a message

This # called twice,looking for donations. I don't donate over the phone,because not enough $$ goes to the actual cause,most of it goes to the fundraisers.

Shows up as AICR on caller id.  Did not answer.

!st call in quite a while, not sure whether number is new or not.  Saved number to phone with silent ringtone.

I have been receiving calls from AICR  for several months and they never leave a  message.  If this is a valid charity I would think they would leave a message.  BLOCKED THEIR # !!

These people called me this morning at 10:39.  I did not answer and no voice mail was left.  My caller ID read AICR as the name of the caller.  I can only assume these guys are telemarketers.

Just got call from this number...caller ID said A.I.C.R.  I let it go to answering machine and no message.  Googled the name and it came up Research for Cancer.  Sorry..NO!

I received a call and also from AICR but there number doesn't actually match the one listed for AICR. Since this is the second non-message-leaving cancer charity I doubt its legitimate but instead a bogus charity trying get money.

Asked for spouse who died 20 years ago.  Charity Navigator gives AICR an overall rating of ZERO.

This number called me this morning at 11:46.  I did not answer and no voice mail was left.  My caller ID read AICR.

Received two calls one at 615 pm and one at 11;43 pm; never answered; they didn't leave message.
