Lost because the enemy had communication

I feel like the last game i played was lost from the first minute. I had entered a game with a friend (Duo queue ftw) and upon entering the lobby a Dreaded "What is draft mode?" came in the chat, from a Draven non the less. This was ok, slightly bad but we've all been there, then when entering the game i notice that the enemy Top, Jungle, Mid and Supp were premade (The club take was all the same) then the enemies proceeded to destroy everything, My jungle was invaded lvl 1 (Stealthed my red while i was getting leashed at blue. Then from there the enemies where able to out coordinate us. What im trying to say is why did this happen? and how often does this happen?
