Hello. Thank you for calling Spend Mart.
Is this the Customer Service Desk?
Yes. How can I help you?
I bought a sweater from your store a week ago. It says size 12. But actually it is a size 10. Can I exchange it?
Do you have the receipt with you?
Yes, I do.
I'd like to apologize for the mistake. Please come on down with your receipt and the sweater to exchange it for the size you want.
Thank you very much.
