this number rings about 5 times each day - I answer and the call then disconnects

Same as above I get these calls everyday so annoying

Caller: Crypto investment scam

Claims I signed up to his database and that I must want to buy cryptocurrency. Thus far I’ve enjoyed keeping him on the line and wasting his time.

Continuous spam calls MULTIPLE times a day!
I'm already blocking every number that comes from "(02) 7251 ***" but I can't keep up with them and now this prefix has started as well!!

Here's a list of the spam numbers I've received lately so search engines to pick them up:
(02) 9071 0075
(02) 7251 2852
(02) 7251 2579

I'm an Optus customer and NEVER had this many spam calls when I was on Telstra and every time I speak to friends about it, the first thing they say is "I bet you're with Optus" - is our number on sold list or something?? There's no point even moving away from them either as my number is already out there now. I've had this number all my life and use it for work as well so I can't change it.

Caller: some investment scam

Prick rang and insisted I enquired about an investment and I assured him I didn't but he kept saying I did and tried to talk over me, I then got angry and said I didn't and told him to f*ck off!

complete harassment , I request not to call and the person was asking tell me the reason. Calls every single day more than 10 times.

Caller: Fraud

They have my full name. Don’t know where they’ve got my details from

PEST CALL

Scam

Comes up as potential fraud, so I blocked

When I tried to call back (while blocking my phone number of course), my call didn't go through. Looking at the 02 7251 XXXX number, there are complaints of scam.
