CORRESPONDENCE SUMMARY / 邮件记录摘要

Omica Chow · 21 October 2026

These are paraphrased summaries, not verbatim emails. Account addresses, case numbers, tracking links and staff names are omitted.

My original X post said I had not received a response. A subsequent check of my mailbox found Support replies dated 30 September and 4 October, plus an AI-assisted reply dated 21 October. That statement was inaccurate as a general account of the correspondence. Support has replied; my concern about the recurring value of the plan remains unresolved. This page and new sharing text use that corrected account. The original post remains linked as the historical record.



30 Sep 2026 — Transition and temporary credits

Support confirmed that my account was eligible to retain its previous allowance through 29 October while the subscription stayed active. It also confirmed a one-time grant of 62,500 credits expiring on 31 December. I acknowledge this temporary benefit.



4 Oct · 08:15 UTC — No verified numerical comparison

Support said it could not verify an exact 20×-to-10× comparison from the published guidance and recorded my objection to the lower recurring allowance at the unchanged price.



4 Oct · 10:15 UTC — A conflicting explanation

A later reply described the change as 20× to 10× and referred to five-hour and weekly windows. This was an explanation in the correspondence, not a figure I independently verified.



4 Oct · 14:10 UTC — The precise claim was withdrawn

Support then said the earlier exact multiplier explanation went beyond published guidance and could not be verified. It clarified that Work and Codex share an allowance, ordinary Chat limits are separate, and Pro $200 did not have a separate five-hour Work/Codex cap. No policy change or response timeline was promised.



21 Oct 2026 — Cancellation statement and a further reply

I publicly stated that I had cancelled renewal. A mailbox check also found a reply dated 21 October, labelled AI-assisted, repeating the lower-allowance transition at the same $200 monthly price. It asked about confirmation of the App Store cancellation. This page does not treat that email as proof of my billing status.



我的原始 X 帖文写了“没有收到回复”。随后核对邮箱发现，客服在 9 月 30 日、10 月 4 日回复过，10 月 21 日也有一封标明由 AI 辅助生成的回复。因此，将整段沟通概括为“未收到回复”并不准确。本页更正为：客服已有回复，但我对订阅长期价值的政策关切仍未解决。本页及新的传播文案均采用更正后的表述，原帖链接作为历史记录保留。



2026 年 9 月 30 日 — 过渡安排与临时额度

客服确认：在维持订阅的条件下，我的账户符合保留原额度至 10 月 29 日的过渡安排；另有一次性 62,500 credits，12 月 31 日到期。我认可这项临时补偿。



10 月 4 日 · 08:15 UTC — 无法核实精确倍率

客服表示，无法从已公布的指引核实精确的“20× 降至 10×”对比，并记录了我对价格不变、经常性额度降低的异议。



10 月 4 日 · 10:15 UTC — 随后出现不同解释

另一封回复将变化描述为 20× 到 10×，并提到五小时与每周窗口。这是邮件中的解释，不是我独立核实的数据。



10 月 4 日 · 14:10 UTC — 精确说法被撤回

客服随后表示，先前的精确倍率解释超出了已公布的指引，无法核实；并澄清 Work 与 Codex 共享额度，普通 Chat 限额另行计算，Pro $200 的 Work/Codex 没有单独的五小时使用上限。客服没有承诺政策调整或回应时间。



2026 年 10 月 21 日 — 停止续订的公开声明与进一步回复

我公开表示已取消续订。核对邮箱时也发现一封日期为 10 月 21 日、标明 AI 辅助生成的回复，重申以相同月费转为较低包含额度，并询问 App Store 取消续订的确认情况。本页不将该邮件视为账单状态证明。
