Ordered a key for zombie army trilogy and it didnt work on steam, contacted HRK support and after providing screenshots of proof, they asked me to contact steam. ( I should not have to do this) Steam said that the key is nothing to do with them and i will need to contact HRKgame.
I contacted them again and there ignoring me. So i lost my money with this company, avoid them and do not buy your keys from here.!
