Called twice and I didn't answer, since I don't know any "C. Fifty". After the third call, I picked up. Man with an accent, wanting to speak to "the lady of the house". After my asking several times what he wanted, he said he wanted to talk to the lady of the house about the A/C system. I told him it was fine and please not to call again and hung up. - It seems that with all our jobs gone overseas, thanks to the last few administrations, more and more scams and gimcrack stuff like this is proliferating because people have to find some way to make money to live. Sign of the times, decline of a culture. Pity.
