update on previous message rang again claimed to work for telstra and our computer not working he was a indian

Sick of this number calling and then hanging up no message or just hanging up think scam or telemarketing

just has a phone call from this number. "John" from Telstras technical department telling me someone had been downloading corrupted files onto my computer and he was going to help me fix it. Had an Indian or similar accent

Number rings. Upon answering says "goodbye"

Like all the above messages, got a call from that number but no message left, and when I tried to call got 'the number you have called is not connected'.

BEWARE I Had a scam call from this number today. Caller claimed to be from Dell and said they had been monitoring my computer for a while and there were errors on it which they needed to fix. They said they would go into my computer to fix them. I told them I was concerned this was a scam call and I'd call Dell direct. I then hung up and reported them to Dell here http://www1.ca.dell.com/content/topics/survey.aspx/ss?ssid=fm8lnRnnMOE~&dgc=SM&cid=279852&lid=5635328 .

This number called me today and when I rang it back it said it was disconnected, seems a bit dodgy to me.

this number rings me i answer then a voice says goodbye. i rang it back and a telstra voice said number has been disconnected how can that be, they are ringing me????
