edit: actually I want to just highlight one particular thing in his match history. His low death count. This is telling me that Interface is playing a lot safer than you do and it's translating to wins.
Looking at the rune pages alone - that definitely needs work. While runes aren't necessarily going to make or break you, they are an indicator of one's understanding of the game mechanics. None of your pages really offer an efficient bonus and mix runes without actually having them serve a purpose. .33% cd is less than 1%. You waste 2 slots on that alone.
My guess is your team is lacking in wards and since you're often in a support role running a tank that you are struggling to get your items as is, let alone wards on top.
Ultimately you probably got into ranked earlier than you should have, as you would probably have done better if you had more normal pvp experience, as well as the champ selection and rune pages to go with it.
With that said - the worse your teammates are, the better you should be at knowing what to do to help them win.
For example, running a tank in the support role rarely works out well. The support sacrifices potential income for the sake of the adc (generally speaking) and as such is going to be the weakest champion when the teamfights come around. Even if you win your lane, you're likely be unable to take a few hits, and the tanks already are significantly weaker as is in season 3.
Your understanding of items could also use some improvement, but really there are plenty of ways you can improve that you simply need to recognize and work on.
You can't control your teammates, and you can't win every single game. However, you can improve your own gameplay and your teams overall chance of winning. People who always write off losses as their teammates fault fail to improve because they never recognize the errors in their own game.
