The business model of these parasites is to "conduct charity calls on behalf of various Non-Profit organizations". In other words they are set up to hound people with unsolicited phone calls. There is an "Opt-out" form on their website but it makes no difference, they still phone again and again and again. Please report them to ASIC. If they get enough complains maybe they will actually do something.

Number not listed in directory, unsolicited call, did not leave a message.

Yet another bunch of nuisance calls. Just block any number starting 02 5133 52__

These scamming scum are simply relentless in their determination to harass people. It's outrageous that it's continuing despite having been reported so often.
I resorted to blocking all calls from (02) numbers but it enrages me that they refuse to give up. They have now called, pretty much daily, from (02) 5133 numbers ending in 5232, 5234, 5235, 5236, 5237, 5238, 5239 and 5243. They are rabid.
Please never - never - answer calls from them, or any other unknown numbers, or this will never stop. (Not that it stops this lot of bottom-feeders.)
I'm about to report it to Scamwatch. Again.

Caller: (02) 5133 5235

If possible don’t give this and other similar calls oxygen - let family and friends leave messages.

Constant bombardment calls to our home and mobile phone services .... I no longer answer calls from numbers 02 5133 52 XX calls from around 4am to 9.30m WST ... 7 days a week. no messages are left by these fraudsters, WHY not leave a message if they are on the up and up and behaving in professional legal capacity according to Australian LAW. These individuals are a curse to people who pay for phone services, go about their day to day business and life as proud Australian citizens do, often to help others less fortunate. We Australians want and need to be protected from these parasites .. Thank you .

These calls are relentless, multiple times a day and when you block one they call from another 02 5133 number. As other have said, no messages and no one on the line when you answer.

Keeps calling but doesn’t leave a message

Same number with 2 different digits at the end.
Calls multiple times a day. They don't leave a message. I now have silenced the ringer and only answer those callers who leave a message.

This number calls us several times a day from 9am to later than 7pm. I normally don't answer bit if I do there is no one there. I hang up after 4-5 sec.

Scam call from 02 5133 set of numbers.

A number will ring me and I don’t answer and they don’t leave a message. So I block it and then I get another call and the number is the same except for one digit.
