If you live in the EU you could threaten them with GDPR, also you have a right to not have decisions made by algorithms without recourse. If you live in US you are pretty much fucked.
Google's policies, as required by their privacy policy, are to delete all data associated with a suspended account in 30 days.
That means any GDPR request submitted after the account is suspended will be responded to on the 30th day, and the response will be "we hold no data about that account".
