It's just 9 cents so I don't want to go back and forth with customer service. But this is quite shady practice to have random charges without notice.
4 stars: nice app with all important information. But if you want to change your contract, then this app will not show you a complete comparison. LTE speed comparison is not shown. This will not allow a fair comparison or decision. In my case I have to contact the hotline for further information and changing my contract data
