Hoi
Ekaterina Welcome to customers helps customers Community of Vodafone.
Several topics about this have already been opened and answered. The best thing to do now is to unsubscribe from subscriptions via www.payinfo.nl.
The annoying thing is that there are sometimes hidden ads in apps or banners that suddenly lock you to a subscription. Vodafone cannot do anything about this either.
For complaints you can contact via the Vodafone complaints webpage: https://www.vodafone.nl/support/abonnement-en-rekening/telefonische-overlast-melden-of-betaalde-diensten-stopzetten.shtml
And read the link below on the Community. You are unfortunately not alone, more people have suffered from this. You can always ask Vodafone if they want to return your money out of leniency (see complaints page).
