What will happen to the paid services and benefits after I delete my account? Will they be transferred to other people?

No, they won't be transferred to other people.

1. After you delete your account, all the items associated with it will be permanently deleted. Such items include usernames, passwords, order history, cloud services, etc.
2. If you decide to create an account using the phone number previously associated with your deleted account, this will be viewed as creating a new account. It won't be linked to your old account.
