You might want to post the e-mail Amazon sent you stating that your account has been suspended. Usually, there's some kind of reason, but it might not be clear. You might want to post that e-mail.
If I'm looking at the right storefront I see that your three feedbacks are all positive. So, bad feedback isn't the reason.
I'm a little worried that you may have waited too long to reply. But, I can understand that if that e-mail didn't specify the reason your
account was suspended that it might be hard to say what you plan to do better.
