Blocked in Bronze 5 impossible to Level up


I recently made my placement games but I arrived in bronze 5. blizzard Having recognized the problem, we decided to level up more quickly. Except that I can’t level up I’m stuck in bronze 5 even though I’ve won the seven wins several times. My friend who played with me and then goes from bronze 5 to silver 4 then to silver 1 while I am still stuck in bronze 5 while I played with him in dps while being the same action of the game.

Please fix the bug if possible.
