When I called back 301-710-5621, I got a long recorded messgae. They call themselves Donor
Services Division and they work with quite a few charitable organizations according to the message.
I live near the Silver Spring,MD area so I was able to get them by dialing  a 1. They have called my house 3 or 4 days in a row.

Caller keeps calling asking for someone by name then a fax takes over. Name unknown,the number is not familiar to this household.

Called just before 7 pm, briefly heard a woman's voice, a click and then nothing

Call..left no message..

Got a call from this number a few minutes ago.  (301-710-5621 in Bethesda MD) The lady asked for my husband and I asked who was calling.  She said her name was Amanda Miller and offerred to call back later.  I asked her what company she was with and she said Medallion and immediately hung up on me.

I just got a call from 301-710-5621 in Bethesda MD.  Didn't pick-up or leave message.  I agree, it came from Waldorf.

I got a call from this number too. The call came on Sunday april 10 2011 I have caller id and asked as soon as I answered who they were they said special olympics I hung right up.This takes about 5 seconds.The do not call list is nothing but a government scam to get the information they already have on you confirmed.Charities and fundraisers etc are all exempt from the list and they are the people who are calling us all.Just answer the phone ask who they are and hang up.

Caller said they were collecting for Special Olympics.  They went through their spill and then wanted my address I then asked how they got my # they said from old telephone directories.  I then knew this was a lie because we have never been listed. Beware!!

Tried to return call but was instructed to use a "1".  Called again, this time with a "1" and the number was not reachable. Go figure.

It hangs up as soon as I answer.  Call it back and a recorded message says "We're sorry, your call cannot be completed as dialed, please contact your attendant." and the message repeats.

When trying to call back blocking aout my number...I get a message "sorry the toll free number you have dialed is blocked from your calling area"...what type of shyt is that I am calling from the 301 area code

Searched the number and it came up a landline in Waldorf, MD.  Looked like from an apartment complex.

This number keeps calling my home phone.
I called the number back and a recording said that they are Donor Services Division.
It sounds like a telemarketing company for charities.
There was no option to be taken off their list.
My number is already on the Do Not Call list.

Annoying...

Caller (woman)said "Thank you" when I answered and then hung up.

They called and hung up

monitored call-when answering machine picked up, heard male voice say "Ooooooh" then people in the background talking about barbecue. This sort of childish crap should stop in elementary school.

The office of Maryland Undemployment. You are probably getting audited.
