You have recently bought a piece of electronics which does not work well Write a letter to the manager of the shop and describe the problem In your letter include what you have done about it and suggest what action you d like them to take

Dear Sir,
My name is Hieu who was one of the customers coming your Myer store in Chatswood in two weeks before. I bought the i-phone cable charge but it doesn’t work when I come back home and use it.

Today I want to write this letter to you to describe the issue of your product. There is not any sign of the power charging on my phone when I put the cable charger to my phone and I think it does not work although I try to put it in and out many times. Therefore, I wonder that you can exchange another cable charger which was tested to work well or you can refund for me as an additional plan.
I hope you can help me to address this unexpected situation in the case that I am a regular client of your shop. Thanks for your help and I hope your business will develop more and more in the future!
Your faithfully,
Hieu
