c'mon Telstra, lift your game

I know we live in a communications black spot, but we were assured by Telstra that we would have no problems with their 3G networking.  Well half of the time we don't, but the other times are soooooo frustrating.  No connections for days at a time, dropping out during sessions etc.  We have rung all the phone numbers we could find to get some answers, even ones that the technicians have suggested that do not appear in the phone book, only to be told that there is no problem with Telstra, it must be our equipment.  So why do others in the area have the same problems??????  Getting very pissed off at having to pay for a service that is not reliable.
