Matchmaking system in league isnt fair

well i was playing on my main account past 2 days and i was trying to catch up in wins but as soon as my win streak became like 5-7 in a row and the tie between wins and loses became 2 games i started playing games that contained at least a gold or plat player and i am not even ranked how is that fair ? they were all killing me except for 2 or 3 wher i won lane against them will this be fixed someday ? look at this http://prntscr.com/gggmw0 [cass-cry] IT SUCKS :(
