Amazon suspends thousands of sellers on a daily basis. You are not alone. Your account could have been suspended due to Intellectual Property Rights violations of following types:
Know that it is the responsibility of an Amazon Seller to resolve their infringement issue with the rights owner before Amazon will reinstate their listings.
Straightforward way to get your account reinstated is to get the intellectual property rights owner to withdraw their complaint against you. That is likely to fail more often than not. Right owner would not have filed a complaint against you in the first place if he was to withdraw it.
Prepare well – Do not rush into submitting something as soon as your listing is blocked. Reinstating a listing takes anywhere from 10 days to a few weeks. Do not waste your appeal without proper preparation. Most suspensions require a few communications with the Seller Performance team. Prepare and submit a most effective appeal.
