Hey there! Nice to meet you!
Based on your description, just to confirm, you are unable to sign in to your account and the error message you received is "Too many requests" is that correct?
If yes, to clarify, have you forgotten your account's password by any chance?
Do you see any unfamiliar email address/phone number upon signing in to your account?
May I know the exact troubleshooting steps you have done so far to fix the issue for us to make sure we're on the same page?
In the meantime, please try to follow the Sign-in helper tool in case this would work through this link:
Best regards,
Darhyl
