What do you mean by "my previous €12.99"?
Do you mean the second €12.99 charged when you bought your first €12.99 plan?
When you buy your first membership plan for €12.99 an additional one-time activation fee of €12.99 is also charged.
That's where the €25.98 comes from:
€12.99 Plan
This €12.99 Plan is only available to new 48 customers who order their 48 SIM and purchase a €12.99 Plan from the 5th April 2022. A one-time activation fee of €12.99 applies with the first plan purchase.
When the first monthly plan has run its course and expires then you need to buy a new €12.99 plan.
The one-time activation fee doesn't pay for any plan.
Occassionally and for a time limited period 48 were giving new users the second monthly plan free which effectively cancelled out the one-time activation fee but that offer is no longer running right now.
E.g.:
