Quoting from the staff Welcome Guide:
.Complete F1 requests whilst online, on duty or not...
.Be Proffessional
Clearly Kevin was very unprofessional while dealing with your case, even if the F1 menu was bugged and he couldn't see your request, he should have responded, rather than saying that he can't help you because you don't have a pending F1 request.
I would like to see what Kevin has to say about this...
