255220-3

i have an error with no words just numbers 255220-3 , so i contact technical support and complain about 5 times and nothing happen, i can hardly complete 1 game per day and some times i can't ,that error comes in any mode, it makes me disconnected from server in 10 sec's , when i contact support and complains all what i got is : please don't make more tickets on the same problem !
it's about a month now with this error and nothing happened, i still got it every game i play .
i know there was a previous thread about this error but it's really become sooo annoying .
i reinstall the game twice in different places, did a clean reboot, installed a new windows version, checked my internet connection twice, everything is good from my side .
i sent this thread yesterday but i think no one from the support team saw it so some help plz, i just want some attention/help from some one who's really care and act

tnx
