Daily multiple calls. Answer and they hang up. Call back and it has an option to opt out by pressing 2 and it just hangs up

I've also been harassed by these ratbags. here's their website address where I rang them & told them in no uncertain terms to go f*ck themselves:

rings my mobile two to three time a day. now i'm just cancelling ring

every day same time, if no one talks with in 2 secs and has white noise in background = hangup!

Answer phone, they hang up! Time wasters..

Telemarketing calls from TSA Telco (subcontractor of Telstra). Despite me telling them and Tesltra to take me of their calling lists, teh calls persisted. Had to get Aust Communications and Media Authority (ACMA) involved.

I ignored the call. They didn't leave a message.

I have had these people calling continually and as its a similar number to a sick friend I have listed it under DO NOT ANSWER on my mobile as it is confusing. This is spam phone call and should not be allowed under the do not call registry.

I've been getting a bunch of these. I never answer and they leave no message. I believe it's TSA, which is notorious as a seller of Telstra services (but not part of Telstra) through obnoxious telemarketing.

I'm receiving many calls from this number and am overseas so getting woken by these calls throughout the night. When I answer there is no one there. I tried to call the number back but no one answers.

they've been doing this for over 2 years? this is ridiculous. Even when I answer they don't talk! what the heck?!

Its Telstra account management trying to 'upgrade' your service.

I didn't answer, and they didn't leave a message

Sxith and seventh time yesterday! Still no message.

And now a fifth time! I'm sure they'll give up soon!

This number ring the business phone and hang up when you answer. Annoying.

To stop receiving calls from (08) 6228 4010, call TSA Telco Group Head Office in Perth on (08) 9327 4098, and request that your number be permanently removed from their telemarketing lists. Should be handled instantly. Was invited to call them back next week, if we do happen to receive any calls.

And again, still no message and I still refuse to answer!

And now a fourth time, still no message! Hopefully they'll give up.

Its Telstra
