The person I believe you are attempting to find is listed as the Co-ordinator at
http://cservice.undernet.org/people/
CService Like Undernet is not actually owned by anyone, it is committee based, Committee members are those known as CService Officials and CService Admins (basically most of the people on that people page above).
If you wish to ask something specific please do not go straight to the Co-ordinator, they usually will not listen to user complaints, instead start with the following:
cservice@undernet.org - Our main email address for any and all general enquiries
cservice-abuse@undernet.org - Used for reporting CService and X related abuses
usernames@undernet.org - for anything and everything specifically related to your username
This Forum - general help.
#Usernames - Quick access to username related help.
or #CService - Quick access help channel for anything related to X and channel registration.
There are more options here, please feel free to ask in the appropriate place above.
:)
