@jejujinfarm nim 
what? you went there and didn't get help
why do they call themselves a service center
the staff told you - you can do that yourself?
boooooo!!!! that's a terrible service
why would a client go there is they already know what to do 
or did I not get it right?
I hope someone helps and coach you out from here
maybe .. @sochul nim? 
speaking of which .. I haven't seen that block a long time :)
Cheer up!
