It's a scam.  They want money.

Ben called me out of the blue and asked that I please give him a call back with a copy of my electric bill so they could apply savings that it appears I may qualify for!!!  he sounded very rushed and but did mentioned that he would be at his desk for a bit and could be reached at his direct line 847-423-0080
Ben mentioned it takes minutes to do and it's free too! Wow! We didn't even ask for these supposed savings (they came looking for us!!)  Is that great?! Not really...blocked.

Got the exact same call as Chinatown1980, cell and home numbers
Thank

They asked for "Michael". I said "No such person here" and hung up. There is no Michael here.

Received a call from this number and Caller ID says Ellen Coghill, but person calling identified herself as Windy Miller of The Medical Benefits Dept. Records indicate that either you or a loved one was prescribed Invokana and may be entitled to compensation. Please call me back today at 1-866-226-9914 to discuss this further." Never heard of this drug and don't take medication!
