Call about Victorian Energy Upgrade

Would not stop calling me over several weeks. Often left messages that were just background noise and random mumbles.
Nothing important.

Despite having'do not call' number called telephoned offering home. Had an Indian accent. Told the caller to f*ck off and hung up. Kept calling back. Reported to Telstra.
Offering home renovation services

Caller: Dream 'something' Services

I usually get a call couple of times a week about replacing air conditioning vents (which I don't have), replacing shower heads, bulbs and all that. I'm trying to track down the company. It's so annoying I tell them I don't have air conditioning vents yet a week later I get another call.
