Caller: Unknown

Unsolicited call offering a deal on an electric solar system and their solar person would call me to explain how much money i would save etc etc. Eventually asked if I already have solar. I explained that I do and I don't think I am allowed to have a second system so this has been a wasted phone call. Their response was "Do you have a second property where you want to install solar". Very pushy.

Multiple calls, telesales, don't answer!!!

6 calls in three hours. Not leaving messages. Sounds like a telesales or call centre.
