Sorry to hear that you're still without a connection - this is taking far too long and it sounds like there has been a lot of back and forth with Telstra regarding this.
Unfortunately, due to similar issues in the area, Telstra technicians are experiencing overwhelmingly high workloads and tech response times are longer than normal.
I've made a follow up to our Engineering team and has requested to have a call to discuss this case with you tomorrow, between 11am - 12pm.
We completely understand how much your service means to you, @SandeepK. Our Engineering Team is working around the clock with Telstra's full cooperation to get this issue rectified, we'll pass this to them for additional reference. Further updates will be provided by the assigned Engineer handling your case.
Our Engineering Team is still waiting for commitment schedule given by Telstra. I will pass this to the assigned Engineer handling your case for additional reference. Feedback will be provided once update is available.
