I picked up the first call and there was no answer, so I called back and someone picked up and said "hello" and then another voice came on and said thank you for calling "Green Energy blah blah blah". Sounded like an amateur scam operation.
If you have call display, you can see who is calling you. If you don't recognize the number, my advice is... don't answer the phone. If it is important, you'll get voice mail from this number And..... I haven't. So, No problem.
Received a call asking for home owner. I immediately said I wanted nothing and to remove my name from their call list and never call back - they hung up. That pissed me off so I called back and asked for a manager they refused. The guy then proceeded to do his sale spew! I interrupted him and he said why would I want my name removed. I said I don't need to provide a reason - just don't call! He hung up on me. I am royally pissed off!
