商家不退款怎么办：一封有效的维权信长什么样The merchant won't refund: what an effective demand letter looks like

买到问题商品，客服一直拖着不退款，下一步该做什么？The product is faulty and support keeps stalling. What's the next step?

先固定证据，再谈判Lock the evidence before you negotiate

很多人一上来就在客服窗口吵，吵完发现关键截图没留。顺序应该反过来：先把订单页、商品描述页、问题实物照片、以及客服的每一次答复截图保存（含时间戳），再开始正式沟通。证据齐了，你的措辞才有底气。Most people argue in the chat window first and discover afterwards that the key screenshots are gone. Reverse the order: save the order page, the product description, photos of the defect, and every support reply with timestamps visible — then start the formal conversation.

维权信的四段结构The four-part structure

① 事实：按日期列出发生了什么（下单、收货、发现问题、联系客服）② 依据：说明为什么应当退款（与描述不符/存在质量问题）③ 诉求：明确金额与方式 ④ 期限与下一步：给 7 天，并写明逾期将向平台投诉或发起支付争议。四段各一小节，不要写成一大段抱怨。① Facts: what happened, by date (ordered, received, found the defect, contacted support) ② Basis: why a refund is due (not as described, defective) ③ Ask: the exact amount and method ④ Deadline and next step: seven days, then a platform complaint or payment dispute. Four short sections — not one long complaint.

升级次序：从便宜到贵Escalate cheapest-first

商家不理会时，按成本从低到高推进：平台内投诉（最省力）→ 支付渠道争议或拒付（力度大，需材料齐）→ 消费者保护渠道 → 公开评价（最后手段，且只陈述事实）。跳级并不会更快，反而会浪费你手上最有力的一张牌。When the merchant ignores you, move up in cost order: platform complaint (cheapest) → payment dispute or chargeback (powerful, needs paperwork) → consumer protection channels → a public review as a last resort, stating only facts. Skipping steps rarely speeds things up and wastes your strongest card.

写信时最容易犯的两个错The two mistakes that sink demand letters

一是情绪化措辞（人身攻击会让对方有理由不处理），二是威胁自己做不到的事（比如扬言起诉却根本不打算）。有效的信是冷静、具体、有期限的——因为它让对方看到「处理比拖着更省事」。First, emotional language — personal attacks give them a reason to disengage. Second, threatening what you won't do (announcing a lawsuit you have no intention of filing). Effective letters are calm, specific and time-bound, because they make handling it cheaper than stalling.
