I have a unlisted number and I am getting muti phone calls from thisnumber everyday. They are unwanted and need to be taken off the list. My number is 3366703788
I, too, keep getting calls from 410-347-5600, C. R. Dynamics. They should be put out of business. One thing you can try is when you get a call and no one answers, hit the * button several times very quickly and hang up. This removes your number from the callers system and they won't call anymore.
