Who called from 4122235188

Today we received the second automated call from "Household Opinion Research". They claim to be doing a survey, but if you answer the first question no ("Are you on Medicare") the machine says goodbye and hangs up.
If you call them back, another automate voice gives you the option of joining their Do Not Call list.

They seem to hang up on the first call no matter what you tell them.  They may just be fishing for phone numbers which will answer the phone.

I answered. no one spoke. no background noise.

Two days in a row they called my phone number and hung up on me as soon as i answered the phone.

Called two time today did not answer says pittsburgh, pa
