If its done under GDPR they are required to respond when reasonably practical and within a month, they can however extend that to two months if circumstances fit such as a complex erasure.
If its being exercised under CCPA then they get 45 days (extendable by a further 45 if circumstances fit).
There's a fairly good chance they have already began reviewing your request and filtering out things that are exemptable - your Bungie account itself would be that; they simply Anonymize it when they receive a GDPR/CCPA erasure request.
