Connection and Gameplay issues on FC mobile

I am facing continuous high ping issue in FC mobile and sudden ping fluctuations, 100+ OVR players losing ball while dribbling, defenders not marking opponent players, switch player not working properly, pass not working properly, players running away from loose balls, cant switch player nearest to the ball, if developers don't intend to fix such serious issues then just reply that directly while answering, I have no problem in uninstalling this pathetic game with 0 involvement from the developers. At least provide me the game server IP so that I can check if the problem is really from my ISP or not because this is the only game that I am facing issues with... I don't face any problems while playing heavier online games on mobile or PC . So kindly respond and try to check the 1 star reviews of this game in playstore
