I received 2 calls from this number and told me that I won something. The next days, they called me again but I ignored it this time.

As others have mentioned the calls come from different numbers. I answered once but there was no response...another number blocked.
If it is important they should leave a message...NOT!

Caller: A random competition number

Do not answer it is a scam and they continue to call me even though I block their number, they call through another number

They have rung me twice today and I picked up but remained silent and they said nothing so I hung up!

I love reverse number look up as it confirms it is just a cold caller and they keep changing their number!

I called the number back and the person answered with "thank you for calling Ground Control - how can I help you?" - I have blocked the number

Caller: (02) 6188 5929

Not picking up this number. Calling me again and again since weeks. Not leaving a voice message as well.

Spammers....
BEWARE !!!

Can't something be done to stop these scum? I am sick of the calls breaking my concentration when dealing with important matters.

Yes just had three in a row same number so hopefull now all blocked. no idea where got my number

Third call today so far - keep blocking numbers - bloody nuisance!!

They seem to have many numbers

Yet another scam call.

Really hoping that my phone does not have a limit as to the number of phone numbers I can block because as soon as I block one number, they call from other similar numbers!

As others have said, pest caller

And also (02) 9542 3909

I changed my number to private and then I called the 02 number to “Canberra “... back a guy answered and knew that my number was on private asked for my details and then will tell me what the phone was about I asked him where are you calling from and he said South Africa do not answer this call it’s a scam

advised by your site rhis number is spam so have blockex .
