These calls are scams and I found out that thousands of other persons are receiving the same call from the same number.
Here is some information about the telephone number (785) 261-9045:

Most of these persons want to know how these people got a hold of their information.
I do not know how these people got this information but, I told them to call their home or mobile phone company and report this scam to them and see what they can do in terms of blocking this number.
Also, I told them to register with the Do Not Call registry at website http://www.donotcall.gov but, I do not really think this will change anything drastically, because these scammers do not respect this registry.
