I was charged $270 for data roaming which I didnt subscribe to. When I went to dispute my bill, I found myself talking to an iPad robot! Talk about the indignity and dehumanisation of customer care! I wanted to show them evidence that I could not have subscribed to this but of course the robot couldn't examine anything! In the end she 'only' charged me $70 even though I didn't use any data! I find this service appalling
