There is no guarantee that Amazon will release your funds, it depends on the violation, why your account was suspended, and Amazon’s findings after their investigation.

Here is Amazon’s→ Withholding policy

If your account is not reinstated following an appeal or you choose not to appeal the deactivation, after 90 days from when your account was deactivated, you may separately request funds disbursement by contacting disbursement-appeals@amazon.com.

We will conduct a separate investigation to evaluate your account for abusive, fraudulent, or other prohibited activity. During this process, we may request that you provide additional information or documentation regarding your identity, financial instruments, and product sourcing. We may validate any information that you provide with third parties or government agencies.
