They have called numerous times. I answered today and a female voice said hello after I did and waited for me to say something else. Since she called me I didn't say anything and hung up. This is obviously a scam of some form.
Received several calls on my Caller ID, then checked out (202) 367-9440 on an AOL Search which yielded similar responses that this is a scam. Next time this number appeared on my Caller ID I picked up the phone and yelled "Rip-off". They have not called back since April 9th.
Re: Call from 202 367-9440. Whoever is calling from this number calls at least once/twice a day at all different hours but when I answer phone no one is there outside of a couple of times, people "talked" to my answering machine just asking to speak to me but they are "talking" to my message. It is very annoying since these people, whoever they are,call early in the morning and after 8 at nite.
Eureka! Just discovered that if if you press the button requesting more information that you get to a point where a voice asks if you want your number removed from their phone list. Enter your number and a voice says your number will be removed within 30 days. Stay tuned.
p.s. Also will report the number to the Do Not Call Registry at every opportunity for good measure.
