Last year, we found our phone calls were dropping, all the time, and service went off line for hours at a time with absolutely no warning or accouncement. Could not log into billing APP on iphone, and account number allocation and IDS were changed without notification, and login access was unavailable for over 1 year despite repeatedly reporting the issues. Shared DATA on sign up but not allocated to services and therefore resulted in over billing despite assurance this would not happen, $4000 plus over charged. Credit promised for period were the call drop outs and call quality issues, and APP login issues were experienced, however this never came through and the person who promised it forgot about it and denied promising it. Raised complaint to TIO and a gentleman from resolutions called back and promised to fix it but never heard back from them again, despite us following up numerous times. Its feels almost as if staff rotating or position change happens on purpose to discourage the customers to diligently report the issue and resolve it. Operators do not fix problems in a timely manner since they are incompetant and change so quickly and without leaving sufficient notes, that every time a new person comes to take over the issue it has to be re-explained again. No Accountability and no will to resolve, and no anility to resolve quickly and swiftly, even though we spend person $300-400 per month on mobile bill with Telstra they do not seem to care. Current issues first reported August 2016 - 1 year through and not fixed fully. Spend 100s working hours on the phone with no rebate or compensation. Seriously not good enough.
