Answer: 1. Please send me a full refund for the stratus balance ball I recently purchased on your website. Yesterday, the balance ball box arrived empty.
Explanation:
A request for refund should not always be too soft, if too soft then it doesn't show how disappoint and aggrieved you are. Though your lines of respect should always be observed.
A claim letter for refund of payment should not be a letter for request consideration. Since the claim is obvious, then it's not a request for consideration.
When an item was been delivered in place of the item you requested. It shouldn't be a request for direct refund it should be a request to, take back their item and refund your money after or immediately.
The first statement is best for a direct refund letter. Because it shows a peaceful but unsatisfied mode, and it doesn't show more of pleading. It was direct to the point.
