A couple of weeks ago you bought a gadget but it did not work. You phoned the shop, had a conversation with a manager there but no action was taken. Write a note to your friend describing the situation.
In your note:

I describe a problem with the gadget;

explained what happened when you phoned the shop;

say what you would like the manager to do;

ask if your friend has ever faced such a problem and ask him for advice.

I Write a complaint letter of 60-80 words.

I asked the question: "Can modern man survive without information technologies?" Let's try to understand.
Let's start with the fact that the modern world is literally forcing people to use any gadgets whether it's phone to contact people, or Navigator to navigate the terrain, or is it the electronic book, which is much more practical than paper.
Secondly gadgets just help people to pass the time. Imagine you would do if there was no MP3 players, electronic books and games on the phone. How would pass your leisure time, for example when you are waiting in queue on reception to the doctor or riding the bus. 
On the other hand, people are abusing the availability of the Internet or any gadgets and a place to clean the house, do homework, read books, all day they lie on the couch and hang out on the Internet without submitting them doing anything useful. As a result, people lose friends, work, score study. This is the negative side of the dependence.
In conclusion, I can say that the arrival of information technologies in our life plays a more positive impact than negative. Availability helps us to grow. I think people just have to learn to use new technologies for the benefit of himself.
