2 missed calls on my mobile yesterday; I don't answer calls from numbers I don't recognise.

Yes, it appears it's a charity. However, cannot get through to them on telephone (03) 8525 6902, despite many attempts = call dies after about four rings.

Yes, I've had the same experience - also in Perth. I read somewhere that it is charity people wanting to work out when residents are home so THEIR callers can make contact. Not sure if this is correct, but am refusing to buy any more tickets or donate to any more charities...via telephone calls.

Same service annoyance from (03) 8525 6902 .
Many repeated calls from this number to my UNLISTED home number in Perth - NO MESSAGE LEFT.
When I try to call the number, the system disconnect after four rings = unable to get through. I have reported the number to Telstra and Optus, hoping they as the larger carriers can check further.

Also reported to Police in relation to harassment

These are pests !!!!!
I m reporting them to Police for harrassment
