Who called from 2076215000

When I call back this number I get "Im sorry, but the extension you are trying to reach is not available. Please check the number and try again"

If you google the number it comes up for unemployment, although they don't use that number

I got the same thing - I didn't know who it was so I didn't answer.  Called it back and got the same blasé recording.

It is safetyworksmaine.com.   It gives free safety classes and OSHA certifications.

I got a call from this number and they said they were from the Maine Revenue Service. And they asked me about my previous names. And they told me I was getting direct deposit. any advice on what I should do?? I just called the number back and got that same message.
