First of all login on to your cracked account
Create a cloned email like that of the owner. For Eg: if the owner’s email is: IAMCRAZY007@gmail.com ; then create a fake mail on the same name like: IAMCRAZY007@yahoo.com
Now is the main task & for this, you will require some brain. Now the task is to convince Netflix customer care support that your account was hacked & you have no access to it anymore.
Now he will send a link to the email and ask you OTP (this may be optional idk it depend ) & you have to say, I already told i don’t have access to it anymore
Now they will ask for another email & also they will ask for payment details too! (payment details you can get at the billing history section) ; maybe they will ask for the last 4 digits of cards or something else
Now you have to provide the asked details & the other mail will be the clone of the original mail you’ve created
Now they will change your email if details were correct & send a change password link to the cloned mail.
Now you’ve successfully changed your email & password both & congo you have your own private account.
