Hello !
I'm ............ . I wrote to complain about the mobile phone I bought.

Let me explain to you. When I bought a mobile phone, it still worked fine. A few days after I bought it, the battery of the phone started to drain quickly. No matter how much I charge, the battery will run out within hours of use.
I spoke with your company representative. They said your phone will be repaired within 2 days. But no, I didn't receive any response from them one week ago. And the phone has not been repaired.

I ask that you please consider this issue and repair your mobile phone or exchange it for a new one.
Hope you will review my requirements and do the necessary things.

Goodbye !
