I do, and i've just recently got a Credit Card with NAB (The same time these calls have started)
last night they rang me at 7pm trying to tell me they could cut my tax in half

Nope must be more than selling a home, never owned or sold a home and they called me.

This is a telephone marketing company.  Today they called me on behalf of Conveyancing Works asking if I needed any financial services, conveyancing, etc.
If you get a call from this group it is probably because you have bought or sold a property in the last 3 months or so.

I tried calling the number back but it is permanently engaged!
