Banned confused

Hello,
this is my situation:
after enjoying the game for some time now and grinding to rank 90+ , unlocking most weapons i wanted to try some of the guns i havent unlocked yet. I read positive reviews on some of the singleplayer guns. I was not wiling to invest hours into singleplayer just to try out some gun i would play with only a couple of times. Hence i resorted to a trainer. What do you know banned.
So im like: ok ill sit out the 1 day ban and then waste my time playing singleplayer. Today i decided to return and play some multiplayer. MY PROGRESS WAS GONE.
Is this a bug? Or is this intentional? 
Is there a way to get my progress back or do i have to grind again? Atleast im unbanned but still, wanting to unlock a gun reverted me to having no guns at all feels kind of sad.
can anyone help me?
or atleast crush my hope of getting my account back
 
btw. the trainer i tried to use was wemod

Сегодня создал новый акк тк старый забанен панкбустером и я не могу зайти не на один серв, создал, поиграл пол часа на этом сервере, стал много обходить и убивать в спину с грозы, так за мой бан проголосовало человек 8 и кинуло в бан, что делать не знаю так как у них кажется своего форума нету и писать просто некуда
