It continues at the stage of post purchasing behavior. This process step occurs when the customer purchases the product. When the customer is not satisfied with the basic needs of the product then this step occurs. In this process the customer can take action to improve the quality of the product or customers can replace it with other new products.

Customer experience can alert another buyer regarding that product quality bad or good.
