A letter to report problems

Dear Sir/Madam

I am writing to complain to you about my camera.I bought the camera from your company a week ago,but I am sorry to say that I am disappointed with it.There are two problems.

First of all,as Iwas opening the box,I noticed a small scrath on the glass.Next the camera didn`t open.

Could you please send me a new camera or could I please have a refund?

Thank you.I look forward to hearing from you.

Yours faithfully
