Dobrý den, ráda bych vás poprosila o kontrolu mého domácího úkolu. Nejsem si tím na 100 % jistá, takže kdyby se našla nějaká dobrá duše a pomohla mi, byla bych moc ráda. Děkuji. 

Mr. Perry,
I am just writing to complain about my iPhone, which I bought from Apple Store in London, on 18th April 2018.
In the begining i was satisfied when i was using it. Everything was alright. But two weeks later i found that phone was faulty.
There are two main problems with this item. Firstly a battery does not work as it should. My iPhone turned off after four hours and I detected that the battery is discharged. I had to recharged it.
Secondly the display went blank. I tried to restart the phone but it did not work.

I am returning the item. I expect you to send me a full refund of price.
Yours sincerely .......

Dear Mr. Perry,

I am writing to you to complain about my iPhone which I bought from Apple Store in London on 18th April 2018.

In the beginning I was satisfied when I was using it. Everything was fine, but two weeks later I found out that the phone was faulty.

There are two main problems with this item. Firstly, the battery does not work as it should. Secondly, my iPhone turned off after only four hours and I found out that the battery was discharged. I had to recharge it. Thirdly, the display went blank. I tried to restart the phone but it did not work.

I am returning this item. I expect you to send me a full refund.
