Key points in this article
Disputes start small
A card that double charges or fails to start becomes a dispute when the user has no record and the staff has no context. Documentation ends most fights. Typical cases are a charge with no session, a session with no charge, or a card refused at a working pile. Each needs the exact symptom captured.
On site handling
Crews pull the user's saved record, match it to the system log, and resolve by the agreed terms. Evidence, not memory, closes the case. Repeated card disputes point to a reader or process fault. Fixing that root, not just refunding, stops the next user from the same plight.
Field principle
Dongshang New Energy treats a card dispute as a signal, investigating the equipment behind the complaint instead of settling and forgetting. Document the exact symptom and most card disputes end before they sour, because evidence beats memory every time. Fix the root, not just the refund, and the next user is spared. A recorded fault at the reader points to the cause; a silent refund only hides it for a while.
