Your game does print congratulations.
I think the problem is that there is a character remaining in the buffer when you break after printing congratulations.

If the player wins, the else part of (key==27) condition is performed.
The getchar() gets the remaining character in the buffer which is not 'N' so the game continues straight away.

I don't know how to clear the buffer though.

if (key == 27) {
    printf("Do you want to quit ?\n['y' yes / 'n' to reset] : ");
    if (toupper(getchar()) == 'Y')
        break;
    else
        continue;
} 
else {
    printf("Do you want to play again ? [y/n] : ");
    if (toupper(getchar()) == 'N') {
        puts("\nThank you for playing and Have a Nice Day!!!");
        getch();
        break;
    }
    else continue;
}

std::endl; should flush the buffer, it is the main reason I use it over "\n"
