How to ask for a refund and actually get one

Hi [Company name],

I'd like a refund for [item], order [order number]. It arrived not matching what was listed, and I'd rather return it for a refund than keep it. Let me know the next steps, and whether I should ship it back or if a photo is enough.

Thanks,
[Your name]

Hi [Company name],

I've generally had good experiences ordering from you, so I was surprised when [item], order [order number], arrived in the wrong condition. I'd like a refund rather than a replacement this time. Happy to send a photo or return it, whatever makes this easiest to sort out quickly.

Thanks for your help,

Hi [Company name],

Order [order number], for [item], arrived faulty, and I'm requesting a full refund rather than store credit or a replacement. Under consumer protection rules I'm entitled to this, and I'd like it processed without a lengthy back and forth. Please confirm the refund and a timeline within five business days.
