I called back the number 0466 170 835 and reached vm that did not mention the company name

Caller: Solar Solutions

A guy from Solar Solutions offering free quotes

Caller: I don’t know

If you don’t leave clear message with who you are & what you want I will not speak with you

0466 170 835 rang phone. They did not leave a message, so I will not be phoning them. If you want to speak with someone, leave a message. I am not that desperate in life that I need to call back random numbers I don't know. Perhaps once people stop rewarding these call centres with a callback they will stop this method of harassment?

I called back and got voice message, no company name mentioned either.
