Unfortunately, there is no 100% sure way to bypass iCloud protection. Not even Apple can help you regarding this issue. Activation Lock is an anti-theft system, it cannot be bypassed. Our suggestion is to ask for money back from Amazon. Or ask them to provide you Apple ID and password. That’s all what you can do. Hope you’ll find solution for this problem. Please, share with us. Thanks. Regards.
