In feb, I switch the monthly scription to Base0. Because there is some data left in my account, I thoght I was consuming these data during march. And I havn't find any updates about the usage of everyday in App. So I don't know how much I used, and I havn't noticed I am not using the data left by feb.
Until march 8, when I receive the message about bill, the Apps updates and shows the usage.
Base didn't remind me during past month. I can't lookup my usage so I consume 400 euros without my noticement. As far as I know, user will receive the remind when usage exceeds 60 euros.
I am a student and I really don't know how to deal with it...Do you have an idea and help me? Thanks!
