pc is really grinding my gears with this input lag

been trying to get in touch with ea help for the past week who gave me 0 info about when it is likely to be fixed. requested a refuld because the game is unplayable. the games registering my inputs then only doing the animations about a second later. its not a hardware issue or a ping issue. and im not getting any form of reasurance, compensation, any cards to at least do sbcs in the mean time or at least a target date for the fix. i want to play the game but thats appauling customer service when they have as much info or less as i could find on this site. the team need real ability to help. and ea need real ability to fix it seeing as ive missed a week and got relegated and lost all the champs matches i played cos of the input lag
