I use Telstra products because 1) I travel a lot in country Australia and Telstra has much better coverage than their competitors, and 2) they are no worse, customer service wise, than their appalling competition, and I have tried 3 of their appalling competitors so I know what I am talking about.
I recently bought a Telstra 4GX BUZZ Mobile Phone. It took 3 weeks to get it to work and a whole heap of very poor customer service. I could not find any documentation regarding how to use it. So to the extent that I use it I have worked it out myself by trial and error. Imagine how much more productive people around the world would be if they were able to easily access good documentation that effectively and comprehensively described the use of their devices. Imagine the time that would be saved. Time is money.
I wrote to Telstra, the Telecommunications Industry Ombudsman, the ACCC and the Federal Communications Minister and none of them gave a damn.
So much for consumer rights in Australia.
