I don't know who they are. I got a call from them too. My caller ID says "Safety Services." All I could find is that it is a land line provided by Qwest out of Omaha, NE.
safety services is a legitimate call and not a solicitation. however the calls you describe indicate a use of an auto dial system. maybe there are problems with the equipment they are using or interfacing with the phone company
This phone number is used by Safety Services, which uses an automated caller. Their main phone number is (402) 895-2984. I discovered that if you call this number, you can ask to be taking off their calling list.
I had a gentleman call me from saftey services at 4028961815 and they asked for my husband I said he was at work and started to say This is his wife how may I help you and he talked over me and said THANK-YOU and hung up HOW RUDE. So I called back and it rang and rang then I looked up the number and found this site with the main line 14028952984 so I called it and let the gentleman know what just happened and he said he was going to do a records search and find out who called and write them up because they are breaking procedure. LOL if you dont like the job dont do it, plus they are trying to get donations for the sheriff department they shouldnt be so rude if they want donations.
