Here's the translation and corrected version of your text in English:
I will never forget the day when we won the grand prize. It was on February 21st, in the Neftegaz (oilman) venue. We danced the "Tatarochka" dance, and there were only seven girls: me, Enkira, Kira, Katya, Sonya, Samira, and Angelina.
As always, we participated in the competition, which had two rounds. In the first round, the judges selected the dances they liked, and in the second round, everyone danced the chosen performances. Naturally, we made it to the second round. Before that, we were feeling sad because we had been scolded for not smiling. On that day, we danced "Home with Victory." It turned out that not everyone smiled, and we were reprimanded.
After that, we congratulated our boys at school and went home. Then we gathered and went to the Neftegaz. Eventually, we waited for the finals, and we performed last. When our team was announced, we stepped onto the stage. Then we were told that we had won the grand prize — the only ones to do so! We received a certificate worth 8,000 rubles for the Truffle store. We were all so happy, almost on cloud nine, and that day will be remembered for a lifetime!
