Attorney Demand Letter for Refund

I purchased a custom bar-wine cabinet from a custom furniture maker, paid in full, and the merchant is using delay tactics and changing the design. I have already drafted a detailed demand letter requesting a complete refund and an alternative. What I need now is a licensed attorney who can do a quick review of draft and place the finished text on your letterhead, and send it to the merchant.

The tone must stay formal and assertive, leaving no doubt about my intent to pursue further remedies if payment is not made.

Deliverables
• Red-lined feedback on my draft, if any, and a polished final letter in Word and PDF
• Final letter issued to the merchant on your firm’s letterhead with a copy to me
• Proof of dispatch: email confirmation plus send regular USPS mail

Please let me know how quickly you can turn this around once you receive my materials—ideally within 48 hours.
