Fleet Arena, Ranks droping problems.

Ok let me starts, been a fan and player of this headache gane for a few months, I have a few strong ships with 6 stars and upgraded, so Im trying my absolute best as well wasting my time to rise mu Fleet Arena Rank to get sone crystals like everybody else and I think I will never get there cuz the Game drops my rank twice now, I was in Rank 107 before it drops me to 230, then I keep playing and got yesterday at Rank 120 but now the dam game drops my Rank to 245, this is desgustingly unfair and frustrating to the point of beating the one responsable for this nonsense, so please EA or anybody in charge of the game, fix that dam problem cuz it's really unfair and a waste of time to keep playing for nothing.
