Ms. Joanne Bauer CallsApr 18, 2018

Can't find a number to call you to tell you someone was here saying that they were from National Grid. I do not believe they were. They did not have your logo and wanted to see if he could see my bill so he can lower my cost. I did not believe him so I made him leave.
