So basically Telstra screwed me up yesterday and mistakenly deducted all of my main credit for internet usage while I had heaps of data and bonus credit allowance. This happened yesterday after I decided to swap from the Encore plan to the newer Freedom plan, I did recharge immediately after that and had make sure I got all the new correct bonuses. By the end of the day I found I only have about $0.01 left at which the web browser redirected me to a 'not enough credit' page. Strangely my data allowance was untouched and call cost got deducted from bonus credit as normally.
I only manage to called customer service when I got back home and got their number over the internet. A call centre staff did a check and told me because my phone (lumia 520) had maintaining its data session for an extended period (including the swap-over whereas I'd lose my old bonuses) and Telstra assumed that I only had main credit left. She then advised me that my best lesson would be to regularly check my phone's internet connection (literally going to setting and toggle on/off data usage) because that's 'how people using smartphone should do'. She assumed Telstra took no responsibility in this. So I requested to put through her supervisor. After that she came back to me and agreed to give me back the lost credit but still maintained her point.
So after that conversation I can't help but wonder how normal, sane people uses their smartphone and come up here to seek some advice. Am I just too slack and deserve to be treated like an idiot?
PS. the lady credited me over $50, the amount triggered bonuses similar to a $50 recharge and I got a whooping 3.7GB of data over a month so thing turned out not as bad.
Not sure what she means by that. You should set it so updates only occur on wifi. Also, you should set it so data connection turns off when you connect to wifi.
