When would like the replacement by

To put several recommendations in action, suppose a part breaks in the gizmo that a customer bought from you. First, take responsibility: "I'm sorry that it broke." Second, don't point the finger--that is, don't say, "We buy that part from a supplier." Third, put the customer in control: "When would like the replacement by?" Fourth, under promise and over deliver: Send it at no additional charge via a faster shipping method than necessary. That's the way to create legendary customer service.


Could you tell me if there is anything wrong with the sentence "When would like the replacement by"? And what does it mean? Thanks.
