英语翻译,如下

1、... 计划1月到6月完成。
... is scheduled to start in January and be completed by June.
或者 ... is scheduled to start in January and end by June.

＊例如：
The distribution is scheduled to start in January and end by July 2008. 供应计划自2008年1月开始至2008年7月完成。
The project is scheduled to start on Monday and be completed by Friday. 这个项目计划从周一开始至周五完成。

2、（我们）计划完成...事。
We plan to complete/finish...

＊“计划完成⋯”没有必要用被动，除非你要表示“⋯事计划被完成”，则可以讲 ... is planned to be finished...（通常加一个时间）
＊... will be completed as per schedule 意思是“将被如期完成”

3、没有被抱怨/没有被投诉
We have received no complaints. / No complaints were received.
或者偷懒一点可以说 No complaints. （建议在写正式report时不要采用偷懒的写法！）

希望回答对你有帮助。

3. Not complain / complaint has not been
