Said they were calling about our electric bill.  Not Florida Power & Light.  Asked them to remove me from their calling list

I think this is a collection agency trying to find out info on someone in the house.  

When this number (407-413-8487) called me today and the lady said she was from the electric company, the lady told me they would be in my area and want to set up an appointment for 30 minutes in the morning or in the afternoon, wanted to know which time would be best for me, and they want to go over ways I can lower my power bill because they said the power rates are going on and want to help me now.  So I said, what, are you going to tell me, to hang different drapes, etc.?  I then asked who she worked for since I figured she wasn't with the power company and she immediately hung up on me.
