### 1/5 — 跑路了，不要上当！

*2026-08-14*

充完钱之后进程一动不动，没有客服入口，上网一搜才知道跑路了

### 2/5 — 尝试了几次一直转换失败

*2026-08-06*

拿了几个PDF测试，但是一直转换失败。如果不支持也应该提示究竟是为什么失败，而不是只显示一个超时。

### 1/5 — 不好

*2026-06-11*

冲了30块钱买点数，转换PDF失败了，已经转化50%还无法从断点重试，消耗的点数也就消耗了，钱就跟烧了一样。

**Developer response:** 你好，很抱歉给你造成不好的体验。请邮箱联系一下我们，附上你的账号信息，我们核实后会做出相应的补偿，感谢你的支持。  support@oomol.com
