You should certainly be able to add charge to bill to your account @richierich2022
Have you tried adding your account by following this link: Charge to Bill
If you have Spend Manager on your account make sure you have not set this to zero or this will prevent you charging to your bill. If you are a new customer Vodafone would also add a credit limit to the account.
If you still have problems, drop the Social Team a message through Twitter or Facebook social channels with a link to the thread and they will help here: Contact Us
edited to add additional information. The accepted Google pay methods are here: Accepted payment methods on Google Play
Unless things have changed, the limit is £30 per transaction and £50 per calendar month for purchases.
I would recommend speaking to the Social Team they will be more than happy to look into this for you and apart from a long web chat or waiting in a lengthy queue will have much more success than going through Customer Service channels.
