I expected phone call, so I answered this one (I didn't answer unknown numbers for years).
She said, she is from Consumers Energy and if I want protection blah, blah, blah, didn't listen, hang up and blocked.
Shannon called and left a message to contact Consumer's Power about our account. I googled the number called from and the number given to call back, 866-858-7377, and 'both seemed to be spoofed or bad calls. I called Consumer's Powers number from my bill and the comment was that it may have been someone trying to have us change power companies or some scam...
left a VM stating it was a courtesy call from consumers energy. they do not have my phone number and i do not owe them any money. called from 517.662.3477 and told me to call 866.858.7377
