I refilled my account balance and I tried to change my plan. My original plan was 'pay as you go' and wanted to change to unlimited text and talk. However, right after I refilled my balance, 3 dollars were automatically taken out from my account. And then I got a call from my friend, so I answered (I didn't call her, she called me). We talked for about 30 minutes and I got a message that I have used all my minutes. Is it normal for money to be taken out even if I receive a call from someone else?
