No 24-hour flat rate for 0.99 possible

According to the description of the use of the mobile Internet for 0.99 euros per 24h is possible.
In reality, there is this possibility does not mean you can surf for 1.49 euros a day from 0 to 24 clock.

I booked the option at 13:00, and stood in the SMS that the reservation is valid only for the current day, not for 24.
So you can surf for 1,49 Euro 24 long, you have apparently Book by 0 clock the PC.

There are vendors with better options (for example, T-Mobile), which deliver what is promised in the advertising.
