Yesterday I performed a small test. Using my cell phone (which is currently on the Anytime 100 plan), I phoned my son's Telecom mobile while he was at school (his phone was at home and switched on). I let the phone ring a couple of times and then hung up. Today I logged in to Telecom and what do I see? One minute charged against my 100 free minutes. The call wasn't even answered! And no, I hadn't left it long enough for Cell Sec to answer. I checked a couple of other calls I know I made and hung up before the call conected and the same thing, 1 minute charged. Now I understand there's a minumum 1 minute charge on calls made, but if the call isn't actually answered this seems a little 'unfair'.
Don't even get me started on the text message the billing system says I sent to my son at 12pm yesterday when I haven't sent him a message in 4 days (yes it charged me for the text at the time).
