I have A problem !! :(

hey guys i was playing warframe but i didn't log in for a long time then when i camed back to the game my credit was -189.454 so i can't buy stuff and i can't use cards can u help me plz??

That's maybe because when there was credit hack u typed a big value so u won so much credits that they went negative ?

Did you use a credit hack, and then buy stuff with the credits?
