Surf Dayflat

Hello, today a Surf-Dayflat (1.49€ / 150MB) was automatically activated on my SIM even though I still have data left in my plan (o2 Prepaid S, about 13GB of 20GB remaining).

Why was this dayflat activated while I still have data available? And is there a way to disable the automatic activation of Surf-Dayflat so it doesn’t happen again?

Hello ​@ThyPham,

welcome to our o2 Community 😀

The Surf Day Flat booking was made incorrectly, and this has since been corrected. If any credit was deducted from your account during the booking process, you will automatically receive a refund. The package will not be booked again.

Here we have informed our users about the incorrect bookings (sorry only in German):

Please let us know if you have any further questions.

Best regards

Giulia
