Porting my phone number from Vodafone to another provider

[bdd]

I applied to port my phone number from Vodafone to another provider. I am a prepaid customer. My new provider told me that I need to share with Vodafone my number porting declaration. I found it requires filling this document and will send it to Vodafone by physical mail. Is there a faster way to process this? like an email address to send the document, I don't want to call support for this. 

Edit: @bdd moved from the Mobilfunk- to the CallYa board, as it is a CallYa tariff
