Who called from 2812415383

Multiple annoying calls from this number - I am on a do not call list

I too am receiving calls from this number with no message.

It's the good ole Energy Efficiency Program as reported here before.

The want to do "green" improvements on your home and get reimbursed by the government.
Too good to be true? I'm sure they can talk you into how wonderful it all is.

How can they be legit when they never leave a message and keep changing their number?

Perhaps if everyone called them back with *67 prefix and treated them the same way they treated those they call, their lines would be too busy to call out.
