Prepaid M plan automatic renewal issue

In Mein o2 you can book a different smartphone option.

However, my plan was renewed even though there was no balance in my account. Every month, I have always topped up manually when my balance was insufficient and activated the plan myself. This is the first time the plan has renewed automatically without my action. I would like to request a cancellation of my current plan or a change to a different one.

As written in My o2, you can change the smartphone option.

Can you tell me how I can do that? 

Log in to the customer portal and check under tariff options to see which pack suits you best, then order it.

Let me ask it again more clearly, and I apologize for misunderstandings.

My main tariff is Prepaid Basistarif, and I am currently using the Prepaid M plan only for internet. I would like to switch to Prepaid S tariff.

However, since my current plan has already renewed and the payment will be taken via SEPA on December 2nd, I don’t want to be charged again when changing the plan. In other words, I don’t want €10 to be deducted twice.

So, in this situation, if I switch to Prepaid S as you suggested, will my current active plan be cancelled and will I only be charged for Prepaid S?

Good morning ​@Ginny_5 🙂
