Cold call (robot!) for solar panels.
Unknown Caller
4 months ago
They have called me several times over the last few weeks. Regularly in the afternoon. There is a robotic voice claiming "we are asking whether your home would be suitable for solar panels, so this is not a sales call". If you were to keep talking to them, I'm sure the sales pitch would arrive pretty soon I have told them to take my name off whatever list they have and that I have no interest in dealing with them. I have blocked the number each time. This one was the latest to call me today at 17:58pm
