I tried to ring back the number (02) 9037 3891 but reached a silent voice mail

Trolls with nothing better to do

Claimed to be Amazon or Home Internet where your credit card is needed in order so your account doesn't get closed even though I don't have either. Press 1 to talk with someone and they hang up. Blocked number so they call from different number or private

Trolls called twice today - nothing better to do.

Have received calls at random times but I'm loathe to answer numbers I'm not familiar with. I realise this doesn't provide great details to assuage your own questions but thought I'd too put in a word saying that I believe not to know the caller/s or have any business dealings with them.
Hope my entry hasn't left you more confused than comfortable! ☺️

Whoever it was didn't leave a msg after I missed the call, I rang back and a deep robo voice said "thanks for calling" and hung up

no message=blocked number

why can't these telephone numbers be cancelled when theuy are reported as scam?

Just went to voicemail, when I listened to it, there was a beep and it says goodbye

Blocked and deleted

Same as above- stupid time wasting scammers/ trolls...I did call back, thinking it was my son from work. D!>%heads didn’t even answer, just ended call 🙄
Blocked!!

Mms received. Unopened. Call has been blocked.

Answered once but hung up, keeps calling. nuisance caller.

They left a message "Hello!".

unknown

Phone didn’t even ring yet was a missed call from 90373891. Came to this site for answers.

They left a "Goodbye" message on my voicemail with a robotic voice. I simply blocked the number

F*#* them, do not answer, BLOCK IMMEDIATELY

spam I believe

It is pretty annoying for this caller who called and always cut out/hang up. No idea who called. I blocked this number.

Hung up after one ring. Returned call only to receive a recorded message which cuts out after a second.
