Answer:
I can see that there are no choices.
You politely explain to the customer that the company strictly follows its return policy. The policy was clear in the first place. You can also turn the return into an exchange, so this doesn't affect the profitability of your business. This strategy can also lessen the negative comments of the clients on your shop.
Step-by-step explanation:
It can be time-consuming when it comes to talking to a frustrated customer. It even becomes harder when that customer tries to return the item late. Thus, it is very important that your policy is very clear from the start. You have to post them on your website, if you are an online shop owner or if you have a website for your shop. This will make the customers aware and set their expectations after making a purchase.
So, this explains the answer.
