167h ban for no reason (again)

as usual im playing comp when my game crashes with error van 1, i have this issues for months and got a total amount of 2-3 month in bans. i went to support as every other time, they said they cant do anything, So what am i supposed to do? my internet is fine although this last few days i have ping issues just as a lot of the community having 30-40 more ping on each server than usual
