Caller: Just another bloody fake telstra -you -have - a -problem

Averaging 2 calls a day from different numbers by these idiots telling me i have a problem with my internet and they are here to fix it for me.
Giant whistle in the mouthpiece???????

caller said she was from Telstra etc etc.I said "You are a scammer!"and she got such a shock that she said no you are the scammer! then hung up!!!

Caller: Glenn from NBN

Had my name and address, then proceeded to tell that there were complaints in my area of line dropouts and crackling over the phone line. He was very slow to proceed to point of his call, but then mentioned something about paying my accounts on time. I asked what this had to do with his call and was he going to get to the point of his call. He just hung up. No idea what he was really after.
