请高手指教我写的有问题伐？

  I regret to inform you that I cannot offer you help at this time to dispose the tooling cases at your locationsolver xla 。 Due to the absence of our supervisor, and the full work load in today's schedule, there is no one available, so I cannot arrange on his behalf。

   If it is not urgent, please wait for him to come back in the office and let him make the arrangementsolver xla 。 If it is urgent, please connect our manager, Mr。

   Hu Wangpensolver xla 。 He will be able to resolve this issue。 Thank you for your understanding。

“I regret”似乎不妥solver xla ，用法少见，建议"i'm regretful"

"offer your help”同上solver xla ，建议"give you a hand"

Due to完全错误(后面应该跟名词性短语）solver xla ，应该为since或because of

对no anyone is free表示费解，根据你的句意，应该把ABSENT后面的AND放到这句前面，因果才成立solver xla 。原因就是下面要删去SO。。

既然用了表示因果的Due to（虽然是错的），就不该用so，去掉即可solver xla 。

(so I can’t arrange on his behalf.这句错solver xla 了）

will be better solver中间显然要加a

最后Thank 改为thanks
