Customer “Kyivstar” I told, how a mobile operator makes money from its subscribers

probably, because recently we have quite often published articles about the activities of the mobile operator Kyivstar, our reader and part-time client of Kyivstar decided to express everything, what's wrong with him.
Migrant, who is currently abroad, sent us a rather long letter about his difficult relationship with the largest Ukrainian mobile operator.
We do not want to act as an arbiter in the conflict, therefore, in this situation, we simply provide the reader with the opportunity to speak out and complain. Well, and Kyivstar will have the opportunity to respond to the claims expressed by their client.
Letter from an angry client to Kyivstar
“ I would like to tell you about... Kyivstar.
Situation #1
I am almost a contract subscriber 20 years old, as well as a prepaid tariff subscriber and in wartime “Kyivstar” took over... , that is, in 2022 year, having connected to the Love Ua tariff, I could use gigabytes of the Internet (12 GB) in roaming as at home. And 2023 years, the amount of Internet was cut by 2 gigabytes, since European partners stopped providing their equipment for Kyivstar’s work in Europe.
But literally a month later, Kyivstar became... in all media, that they have extended contracts and you can use the Internet again in Europe, like at home, but at the same time the amount of Internet in roaming remains the same 2 gigabytes. Also, for the contract, I am charged a monthly fee every day in the amount of approximately 5 hryvnia per day. Adding a minus to me for paying the tariff.
I 3 March called the hotline and demanded that the number be stopped, to which the operator answered me in the affirmative, that he indicated a request to stop providing services to my number and they will call me within 2-3 day.
A week passed - the number continued to work and the monthly fee was charged and then in the negative. Called again: I was told, that no application was received from me, but at the same time they called me, but I didn't pick up the phone (it's a lie) and times 20 repeated, that I want to stop the number from working and I don’t need their services.
Kyivstar suspended my number, but at the same time they charge a monthly fee by number.
Situation #2
Second case: for a prepaid tariff object, when, if there are funds on the account to replenish the account for the subscription fee, the remaining gigabytes of Internet are transferred to the next month. I had times 3-4, when I have the required amount in my account, and it's removed from me 10 UAH. to calculate the daily rate.
When you call the operator it turns out, what "yes, in my account the amount due was, but for some reason the amount was withdrawn to provide the daily rate, they don’t know, after clarification they return the monthly tariff.
At the same time, no one has the remaining gigabytes of Internet last month, as stated, didn't return.
I kindly ask your publication to submit my case for general review., since operators are profiting from their subscribers in such a difficult time for the country and people! Sincerely!
