Rajesh this was not actually a complaint letter. The question is only mentioning that you lost an item and fortunately you have to travel insurance to cover the cost of anything lost.
You are just supposed to describe the three bullet points mentioned in the question itself. You did not mention any of the points in your letter. You did not describe the appearance of your baggage. You did not describe how you lost it and also you did not tell what the insurance company needs to do in order to give you the reimbursement for the same..
As far as the language, grammatical accuracy and lexical resources are concerned, it is a pretty well written complaint letter, however this is not the task that was assigned. So task achievement will take away all the points.
