Welcome to the forum.
I have never heard of dxb. It's the international airport abbreviation for Dubai though. Do you mean you are in Dubai? If so, please click on Edit Post and write Dubai in full each time. Also change "abt" to "about". While you're at it, make sure every sentence starts with a capital letter and ends with a punctuation mark.
We don't write letters for people here. Try to write the letter/email yourself, post it here and then we will look at it.
