I created a customer account directly in Backend based on a phone conversation. Over a while I discovered there is an account with the same data created a year ago by the customer.
I would like to ask:
Why Magento 1 allows two customers with the same data? Why I was not warned by Magento there is already a customer with that email address?
Where will go the orders created by the customer, to ID 3 or 4?
Where will go the orders created in Backend using the account created by administrator, to ID 3 or 4? As I see even I am using this account there are no orders associated to it, all orders will go to account with ID 4.
I recreated this behavior in a test environment and see the image bellow. Two customers with the same data.
