It's Telstra. Why do they insist on harassing their customers so much? If we wanted to do a survey WE would ask them.

Its Telstra doing a survey

why does it keep ringing my mobile

Number (02) 8570 3210 called, didn't know the number so didn't answer. Called the number back on my mobile (hiding my number & ID) and it didn't connect. Strange. Checked with my provider and they "tell" me that if it doesn't connect it'd be telemarketers where they're only able to make outgoing calls. Bugger, was looking forward to calling them back at their dinner/meal time as they called me during mine. Who and why on earth would anyone call between 6 & 7pm. Any fool knows that's pretty much dinner time. I get that they'd know most people would be home during that time, but since also that I'm registered with the "Do Not Call" register and my number is ALSO a private number, how on earth can these telemarketers able to illegally obtain my number? I cannot report to police as the number doesn't connect? Telemarketers should NEVER be able to ring private numbers and SHOULD check with the register prior to calling. Checking back with the register, and the fact that some telemarketer agencies simply refuse to check with the register ("Do Not Call" register) is in fact illegal and can be fined, but since they've gotten smarter & use a line/number where you cannot call them back on renders it all useless. It's most frustrating when you are on holidays at a private disclosure with a private line and still they persist calling. This must stop and the register must be more than just a list of numbers for telemarketer agencies, when a number is private, ALL telemarketer agencies should just adhere to it or devise a system where registered telemarketer agencies simply just cannot connect to private numbers.

3 calls from this number today...?

Called 4 times in 75 minutes in the middle of the day. It's Telstra doing research on how they fixed your issue the week before you wasted almost an hour and a half on hold and then on the phone trying to fix because they buggered it up in the first place.  The questions they ask do not allow you to express yourself or answer correctly.  I'm still waiting for the $300+ credit on overcharges they promised 10 days ago to appear online in my account.

called this morning.

I received this call and do not know the number who is it

It's just Telstra being Telstra. A right pain. Do we provide good services blah blah blah. Short answer would be Not Really.
