I hve been informed from the company that i got a job there, after attemting an interview and asked me to join within 15 days.But i have not received any appointment letter.14 days are over, can u help me in writing an enqiury letter. I need it as early as possible.thank you very much
The interviewer called and askd me that she is going to send the appointment letter

You should give them a call, or go and see them. Don't wait now for them to get back to you. Be pro-active.

Give them a call. Explain that you did not receive the appointment letter and that you would like a little more information. If you wish you can accept the position over the phone and follow up with the letter.

Did she say she was going to for sure? Things can get backlogged adn put on the back burner. I would call it is more personal.
