Don't get me started on Telstra..... OK, you already have

.
As a telephony tech I have to deal with this dysfuntional organisation daily. The most frustrating thing is that I usually have a better understanding of the faults I am reporting and how to fix them than the Telstra operatives I have to deal with, depite the fact that I left the organisation in 1991 when service and service costs were in line with customers expectations.
I've lost track of the times I've had to prove to them the nature of their fault, Telstra's first line of defence is always denial and where they do take action the result is often our company making a trip to customers premises to try and reverse engineer network configs where Telstra have envouraged an inexperienced office secretary to dismantle the whole network, eftpos, fax etc and wipe the router config.
I won't even mention the overseas call centres.....
