asking for advice

i have a littl problem ( and probably lots of silver players like me got the same issue ) : i dodge a lot of matches in ranked because of trollers some moments ago i got placed adc in solo/ duo game and my potentiel teammates ( who aperently were a duo ) wanted to take the adc role .... normally i dont have a problem with that except that im a verry verry very ( X1202166612 times ) bad jungler so i kindly diclined them . here we have jax supp with smite + xin jngl with smite ( and i wont talk about the insults ) i had to dodge earlier in the day so today total losses are just -13 yesterday too i dodged some games and still had a game with 2 suppors intecially feeding and a 5X tear jhin ( 0/12 i think ) had 3 midlaners in another game ap zed support ...... ( ps those listed above i didnt doge cause i had 0 lp at that time ..... ) so if anybody could give me some advice and dont u think that the doding ranked punishment is too harsh ? u know that some times it saves us from a big loss but -10 at a time is too munch especially for some 1 with bad mmr and dont forget the tome penlty sry for the long post and the many spelling mistakes and thanks for anybody who could help me here <3
