Called back and it stated that the number you have dialed is not in service.

I have received 4 calls from this number in the last three days. The male voice kept on saying my name, not sure how he got it, Dave, Dave, Dave. He was not making any sense and I could not understand him at all. I hung up and called the number, but it said it had been disconnected.

Absolute spam. They call saying they're from a lighting company. They wont put you through to a manager and the staff arent very intelligent. Ecovantage is infact a company but work in commercial lighting not residential and are based out of South Australia not Victoria/Tasmania

Could not understand what they were after. I called back and it the message was "number unavailable".

I called back number (03) 9068 9532 it says the number I have dialed is not in service anymore.

They called me on a Saturday, claming to be from a company called Eco Saver and they had helped me install some energy saving led lights before. He tried to offer me other products but I didn't allow him to finish. They had called me the day before, a Friday night, from a different number (03) 8658 9039 saying exactly the same things.
