I just noticed that Telstra's web site shows excess data usage on their Data Pack 10 is $.050/Mb. Not quite sure what to make of that, I had a chat with Wendy, one of their on-line support agents:
Wendy 42164513: How may I help with your enquiry today? Ben: Hi Wendy. I was just wondering if you could confirm the excess usage charges on the Data Pack 10 product. Your web site says $.050/MB, but I suspect it's meant to say $0.50/MB
Wendy 42164513: .50c per meg Ben
Ben: so that's half a cent, or 50 cents?
Wendy 42164513: thats correct Ben
Ben: which?
Ben: half a cent, or 50 cents?
Wendy 42164513: .50c Ben
Ben: .50c strictly means half a cent, but I find that very cheap. Are you sure?
Ben: the higher plans, for example, are 25c per meg
Wendy 42164513: Ben the cost is fifty cents per meg, it has just reduced from 1.00
Ben: Thanks!
Wendy 42164513: You are very welcome Ben
Tiring!
