We get a lot of calls saying that the Gas & Electric Co. gave them my number and I may qualify for a rebate if I have solar panels installed. This upset me to think my G&E company would give out my information and phone number, so I wrote them an e-mail stating such. I was assured they never give out customer information, ever! So if I do get one now, and they tell me the G&E Co. gave them my info, I tell them that is not a true statement and why ever would I make such a large financial investment with someone that starts off by lying to me. Then I hang up.
Now I do what Edie does, it I do not recognize the number it does not get answered. If they want me they best leave a message. My daughter was traveling with a friend, her phone died so she texted me that she was using her friend's phone so to please answer the phone if she needed to call for some reason.
