skua#Telstra's #PrepaidMobile subsidiary #BoostMobile tells me my current plan $230/170Gb/365days has been discontinued.
The only reasonable replacement is $300/240GB/365days. No use for the data, using only ~5GB/mth
And today I find that, contrary to what technical support told me, voicemail has not been switched off. So I had multiple messages that I hadn't responded to.

I've got some 10 months to find a less-ripoff mobile phone provider.
