this number just rang me and hung up (02) 8823 3033

this number has tried to call me 4 times today and whenever i call back it says its "contacts learning" and if i want them to stop calling me to call 1300 135 738 but that number goes to no where as well! just blocked both numbers so hopefully will never hear from them again!

Mine is a silent number so how/why are they ringing it. Surely the telco can shut them down.

(02) 8823 3033 rang and just hung up

should be investigated by the police for harassment

Some idiot keeps ringing me on this number haven't they got anything better to do????...seriously don't even bother with them block straight away 😡

Any number that starts with (02)88233*** are Charity Scams. Whatever you do not give them any information.

every time they ring ,i answer the call and hang up straight away. they hassle me on my home number and mobile

They rang me and presented themselves as a cancer research project and wanted some money from me. They wanted apparently to pay over the phone - i hung up.

Keep ringing my mobile and not leaving a message

I had the same situation happen to me with the (02) 8823 3026 and (02) 8823 3033 numbers on consecutive days. Both times they hung me when I answered.

I just missed a call from this number when I rang back the recorded message  said was an Australian charity

I Just got the same thing but on (02) 8823 3022 missed the call...

Rang them back and it was a disconected number...

changed call ID to not send so phone is private and got the same message you got Damien...

Very strange

Good I read all comments below- been getting missed calls from this number and similar- very annoying- never leaves any messages. don't know how they got my mobile number.
