Prepaid

Hi. The SEPA Mandate wants to deduct money from my bank account. But I just transfer all the money in that bank account to another bank account. And I forgot to change the bank details in Mein o2 app to the other bank. So It cannot deduct the money and now, I cannot use the internet. So now how can I pay the money to O2? I really need the answers because I need to use the internet! Thank you
