This is very unprofessional behavior, and I know there are many scam accusations against them, but now they proved they don't care at all about bitcointalk community.
There might be an error somewhere which may have led to this misunderstanding. For your repute in the forum it's unlikely that BC GAME would want to give you such response for just asking for their interest in sponsoring a competition in the forum.
However, concluding they don't really care about the community is what I am doubt with because they have been major sponsors of come competitions in the forum.
