Caller: Solar rebate call centre

Called me five times in one day from a range of similar numbers. I calked one back and instead of answering with the usual “this is (company name), his can I help you?” I just got “hello?” I had to ask who they were and why they had called me three times without leaving a message.

Something about solar batteries that I can’t have even if I wanted to as I’m renting. Told them to please not call again. Do obviously thry called twice more…
