I have been a TPG customer for 7+ years and i have lost track of the number of times i've called or emailed.
My internet speed commonly vary from 2mb/s to .01mb/s (normally on the lower end).
Everytime i call i go down the same route. rebooting moderm, they check the line, they tell me they have notice on the logs i've had dropouts. Then after i while i'm told that it's my cabling in the house and that they'll send a tech out so my house. Yeah yeah, i've done all that a number of times. In fact over this seven year time frame i have pulled out and replaced my wiring a number of times.
I tend to give up live with the crap connection for another 2-4 months.
On rare occations i do get 6+mb/s, so i know it's possible. But like i said its below 2mb/s a good 80% of the time.
I believe that ISP's have to supply a minimum of 2.5 or 3mb/s connections.
As my connection is below this minimum, this is a breach of our agreement and the ACCC guarantees that come with the purchase of a product or service.
