Are you just joining Vodafone or are you trying to change from your current Big Value option ?
If your moving tariff have you opted out of your current one ?
What have Customer Services advised on the phone to you @KONVIKT ?
There maybe some help in the following link that explains how to go about getting a BVB and there’s also a text service too.
If your still stuck then customer service on 191 or Live Chat should be able to help you.
