Had a few calls from them. Same story, can't call back

I have had approx 25 calls so far from this number in the past 3 weeks. I am over it!! The last call was well after midnight through the week!!

I am sick of getting calls from this phone no. & when you try to call it back noone answers

Have been receiving calls from this number on both my Optus mobile and Telstra home phone for about 3 weeks now. The phone only rings for a short time before stopping. If I ever manage to answer it before it stops ringing, there's noone there. If I try to return the call on the landline, I get an engaged signal, and if by mobile I get a displayed message of "Network Busy" and then it disconnects. Funny thing is, my mobile is in my name, but my landline is someone else's name, so the calls must be coming from someone/thing that I've actually given both my numbers to, but who?!?!?!

Attention!!!Recieved incoming call from (07) 5634 9400.intrusion Alert centre warning.Port ping had been Detected.Response Advisory SlapProg.exeIf it continues escalate response Spike etc.

I am three also... this has been going on now for 3-4 weeks and I'm starting to get really really annoyed. it only rings twice now and hangs up. AAPT you say... will give that a go.

Well, just reporting the same for me tonight - 3 calls in about an hour, hung up each time after I answered - nobody said anything.

Pretty annoying..... if they keep doing it I will report if for abuse and get it blocked...
