Re: Please help me how to write formal email.
A word of advice - everyone here is a volunteer doing this in our free time. You posted your original question at 11.36 and then posted a rather abrupt second post just four hours later. We appreciate that you believe that your question is urgent and important, but there are hundreds of posts here for us to deal with and we do the best we can. Please be patient.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
