Simple newbie question

First off, I am really sorry if my English is bad its my 3th language. I recently started playing ranked games, since I (think) became good and comfortable with a few champions in Mid Lane, and in Top Lane. My first ever game, I was feeding 0/3, But the other one I was playing Talon, and I was good, helped bot lane, destroyed my lane, but no one listened to me when I pinged dragon, or push tower or things like that. 3rd game I thought I am playing normal, with my friend, and it didn't end up well But my questions are for game I played yesterday as talon vs ziggs I was bad in farm, he was harassing me, but I easily 1v1ed him a few times, and I went to help bot few times, top, and in team fights I did my job, their ADC couldn't do anything, and their mid was zoned. But my bot lane was kinda feeding ( I am not blaming them for loosing, I know I could played better) I didn't rage at them or anything, I went and helped them and focused heavily not to get their adc fed, but because I went bot lane a lon, their Top lane Yasuo got like 12/3 and ziggs destroyed my mid turret, and later we lost the game. Could you please give me advices about how to get my team to belive me when I ping drake, or to push tower? And also, some general tips (mostly about decision making, I think that's what I am bad at) Thank you! <3
