cancellation of prepaid simcard

Hello @Ding dong 

Hello, you can cancel your order for the prepaid card at any time by e-mail, please use this e-mail address widerruf@cc.o2online.de and always include your order number and your personal data in the e-mail.

@Ding dong :

You want to revoke an o2 prepaid order or will you cancel an o2 prepaid card?

If it concerns an order, which tariff did you order?

@o2_Maria according to the second comment on my question I sent an email to the mentioned mail address in that comment. I received a reply and customer service mentioned that I just need to simply call my bank and request a refund since the transition is still on hold. 

However, I still don't know if my order was cancelled from the O2 side. 

Worthing mentioning: the customer service in the email did not mention filling out any kind of form for the cancellation. I was only requested to share my identification and the account number from which it was bought. 

If you can follow up and give me assurance that I took all the necessary steps, it will be appreciated. 

Regards
