I called back number (02) 8318 9275 spoke to a woman who said company name is Residential Project Australia.

I always mute the call

Have not answered any of their calls but have literally called me about 10 times in the last two weeks. Does not give up!

Never stop calling; never leave message. Very annoying.

it's from a legit Marketing company that is selling financial packs. especially people who own a home.

Would not take no for an answer, still no idea what she wanted, just told me she was not selling anything but actually giving something away re mortgauge, Australian accent , lots of other calls in background.
