'recently moved to new house' - IELTS Letter

You are recently moved to new house. There has been damage after you move into the house. Write a letter to your landlord explaining what has happen and ask him what you can do? I am wondering I was not sure on topic what to write but I wrote some ideas, I would appreciate your comments and feedback on this letter. I thank you in advance.

Dear Mr Smith,

I am Roshan Panjabi, new tenant at 15C, Strathfield. The reason I am writing because some problems in unit.

I would like to inform you that recently the main door lock is not working and it unable to close properly. Therefore, it is unsafe, dangerous with secure this unit. Another problem, the bathroom hot tap is leaking continuously which need to fix immediately because it is waste of water. Unfortunately, the one of the kitchen electric connection is out of order which require immediate repair. AS you know, I am new in this unit, these problems are creating huge stress in my life.

I would organise electrician, plumber to resolve these problems, however I have just been rented this unit you should repay total expenses. If you are disagree with this idea then I would be happy to move some other unit.

I am looking forward to hearing from you about unit solution. Thank you very much for your understanding.

Yours sincerely,
Roshan Panjabi
