什么情况可以发起拒付（chargeback），什么情况不行When a chargeback works — and when it doesn't

商家不退款，我可以直接找银行拒付吗？The merchant refuses to refund — can I just go to my bank?

适用的典型情形Where it typically applies

商品或服务根本没收到、收到的与描述严重不符、重复扣款、已取消仍被扣、以及未经授权的扣款——这些是最常见且最容易成立的类别。反过来，「买了之后后悔」「觉得不值这个价」通常不属于可拒付范围。Goods or services never delivered, materially not as described, duplicate charges, charges after cancellation, and unauthorized transactions — these are the common, well-supported categories. Buyer's remorse or "it wasn't worth the price" generally is not.

先联系商家，这一步不能跳Contact the merchant first — this step is not optional

几乎所有发卡行都期望你先尝试与商家解决。保留这次沟通的记录（时间、渠道、对方回复），它既是材料的一部分，也决定了审核人对你「是否合理」的第一印象。Nearly every issuer expects you to try the merchant first. Keep the record of that attempt — time, channel, their reply. It is both evidence and the reviewer's first impression of whether you are being reasonable.

材料的排序比数量重要Evidence order matters more than volume

把最能证明「承诺 vs 实际」的两三件东西放最前面：商品描述截图 + 实物照片，或订单确认 + 未送达证明。堆二十张无关截图，只会稀释关键证据。Lead with the two or three items that prove promise versus reality: the product description plus a photo of what arrived, or the order confirmation plus proof of non-delivery. Twenty loose screenshots only dilute the strong ones.

最常见的三个失败原因The three usual reasons disputes fail

超过时限（各家规则不同，越早越好）、没有先联系商家的记录、以及陈述里混入了主观抱怨而缺少具体事实。写陈述时只写可核对的事：日期、金额、承诺内容、实际情况。Missing the time window (rules differ by issuer, so act early), no record of contacting the merchant, and a statement heavy on opinion but light on checkable facts. Write only what can be verified: dates, amounts, what was promised, what happened.
