If the user is wanting to take the phone number to Spark, and you're ok with that, then provide the user your Vodafone account number and name, and Spark will send us a porting request to take the number. As long as the account details they provide to us are correct, we will approve it.
I work for Vodafone, supporting our mobile and fixed customers, and volunteer my time on the community.
