I have been getting calls from them very frequently   when I answer they do not say anything

yeah, they call me all the time too. No idea who it is, they dont answer.

They have called us a few times in the past couple of weeks... they ask for the bill holder for your electric company. It is a scam!!! Search AGR telemarketing on google, the first thing they ask for is your social security #.

I get at least one call a day from this company and when you answer the phone, they don't say anything. They may say hello...but never anything more.
