I am also getting these calls, thanks for info, now I can block this number on my pbx.

I received calls from that 03 number today too. I called the 1300 recommended by JS previously and they said they would remove our number from their listings.

This number rings our business most days, always saying they're from Telstra business.... total BS. Keep telling them we're not interested, but they still persist in calling.

Most of the time the call doesn't even connect.

update:
Suprisingly we haven't received a single call from them since my work collegue made that complaint call to them. (Been about two weeks now)
It's a huge improvement from 3-4 calls a day every single day (even after work hours, we re-direct our work number to a mobile for after hour emergency) to none!!
Businesses that gets calls from them on everyday basis like we used to get,
should consider giving them a call and make a complaint.
I don't feel annoyed or stressed anymore everytime the phone rings now, that's how much stress they were giving me before by calling!!! :)

constant call and hang up 3 x 4 times a day called back number just beeps

Rang numerous times, said wasn't interested and hung up, they then called back straight away with the same call and called me selfish and rude, defiantly telemarketers claiming to be "Telstra"

Just hung up.

Very noisy telemarketer. Very frustrating. Could only hear lots of noise. Trying to tell me that we were getting lots of discounts on our phone line.

We get this call all of the time, who do we call to have them shut down or report them to. All they do is waste our time

Called and said they were from some other phone company. Told him to f#*k off and humg up! Telemarketers!
