Who called from 3474924152

For two months now I get about 2,or 3 calls a day . The name that shows up on my caller ID  GROUP If anyone has any idear let me know Thanks

I too have been receiving phone calls from this number several times a day. My aunt who resides at my house actually spoke to someone stating they were part of the firemen association and were looking for donations. They were told I wasn't home and they continue to call numerous time a day and also hanging up!!
At this point I feel like I'm being harassed.
