Refund request

To Whom it may concern:

I am writing to inform you about the smartphone that I have purchased in your store.

I am a regular customer of your company. On the 10th April, I bought a brand new iPhone 12. However, upon one week of using it, problems started to appear. The flash of the camera is no longer working. Also, the monitor is getting blurry which makes it difficult for me to see the messages clearly. I was very surprised to discover such problems in quite an expensive model.

Naturally, I returned the mobile phone in your store to be replaced with a new one. One of your sale staff told me that they will send it to my home address within one week. However, two weeks have passed without me receiving any replacement. I am very upset for your poor service.

In this regard, I insist on getting a refund of my full payment if the replacement will not arrive within one more week.

Yours faithfully,

Tweety
