[All Platforms][Subscription] How to redeem the Google Nest Mini as a student?

[music161]

How do I redeem the Google Nest Mini (I'm using Spotify premium for students) if my school account doesn't allow the use of Google Payments? At checkout I keep getting the message "your Google Account isn't authorised to use Google Payments. Please contact your organisation's Google Apps administrator". I do not think my school will grant me authorization to use Google Payments if I contact them
