Hi all, I wrote this letter that is an ielts writing task 1. So please help me check it. Thank you all guys so much!

Dear Sir or Madam,

My name is ABC, your customer, who supposed to take the train that was delayed this morning at 7.am. So I write this letter just to let you know about my situation, and I wonder that you can help me deal with my problem.

This morning, I had an appointment with a company for a job interview. It is very important to me, so I decided to take earliest train this morning to get this appointment’s place on time. But unfortunately, the train I have taken was delayed. So I can’t afford to get there on time. That is why I need your help to deal with my situation. And the thing I would like to be helped is your confirmed letter that strongly submits my troubles. It is very helpful to me to get the company’s understanding on that situation. Please send me your feedback as soon as possible. I am looking forward to hearing from you.

Best regards,

ABC.
As this is for a test, I have highlighted below some areas you need to look at again. Your letter also does not make it clear what you expect the person to whom you are writing to provide.

Dear Sir or Madam,

My name is ABC, your customer, who supposed to take the train that was delayed this morning at 7.am. (Do you need to say 'this morning' and 'am'?) So I write this letter just to let you know about my situation (This doesn't sound quite right for a letter of complaint), and I wonder that you can help me deal with my problem.
