怎么用英语写催促工资的邮件应该发工资了,可是老板还没有发.怎么用英语写邮件给他,催他发工资?

Dear Sir,
Sorry to interrupt you.But the issue we've encountered really need your kindly help to sort it out.
As you know,our scheduled salary payment day is 5th of every month.But recently,the salary payment was delayed without any notification and this situation has lasted for serveral months.Especially in this month the payment hasn't been received till today,which brought a terribly cash flow issue to us.
Pls.could you let us know the actual salary payment date in this month?And we'll highly appreciate that if the monthly salary would be paid on a prompt basis.
这个口气应该够客气了吧.
