Safety Before Billing
Even a fee dispute should not push a user to force a session or bypass a safety step. Safety stays first; the bill can wait for a correct fix. Most fee errors are harmless to resolve once the scene is safe and nobody is improvising around live current.
Where Errors Repeat
The same fee mistakes return: unconfirmed session close, unread receipt, retried payment that double-charges. Naming these lets the team target them with clear guidance instead of scattered fixes that address the symptom but never the habit behind it.
Handle Calmly
Dongshang New Energy trains users to stop, confirm the close, and record the amount, because a calm, correct routine ends more fee errors than any sophisticated tool bolted onto a process where the human step was the actual problem.
The fee error is rarely about money; it is about a skipped confirmation. Find the repeat points, slow the user down at exactly those moments, and the billing complaints that filled the inbox simply stop arriving.
