Why do people not listen to calls

For the past couple of months I have been playing a lot of ranked in League, I carried myself out of bronze 1 to silver and now I'm in silver 5. And i'm really starting to wonder when people will listen to legit calls, for instance i just played a game as syndra mid and stomped my lane opponent and from there on out helped out some of the other lanes form there we got into late game and well there adc was just A little to strong and there jg was doing really well too. from there on out (this started around 25 min in) I was trying to tell them "group mid, our team comp is A lot stronger then there's" and every now and then they would listen and we would ace them. What i truly don't under stand is why after the ace keep in mind were 30 min at this point and the adc would go and farm bot, jg would farm top top would do nothing in particular and sup would just sit next to me, but here is the kicker they would do all of this while they had an open inhib and baron was up with the enemy on a 50 second spawn time. with the whole time me saying "push push push there is an open inhib" and from there we lose. WHY DO PEOPLE IN LOW ELO DO STUPID CRAP LIKE THIS HOW CAN I CARRIE OUT OF THIS? oh and then i got a verbal abuse report for no reason
