Fashion Nova review: Refusal to cancel unfulfilled order

Refusal to cancel unfulfilled order : order placed at 8:00am and request sent to cancel order at 8:01am, february 13th, 2019. Instructed to either:

A. Tell carrier that I refuse to accept the package (at which point it will be returned and a credit issued)

B. Accept the package and return the items with a request to refund the order.

Point being is what type of company does not allow you to cancel an order placed in error, especially minutes after it has been placed and not fulfilled by their shipping department.
