5 to 6 calls a day.
Never leave a message.
First call of the day is always at 6am and the last call can be as late as 9pm I answered the first few times. I don’t own a house and there’s no way in hell im giving out my private details WTF.
Give it up. Stop wasting my time ...

I called back number (03) 8372 0165 rang 5 times then goes to busy tone.

These creeps are nothing more than an annoyance to gutless to leave a message which would expose them and their organisation to public scrutiny.
