[PAT THE REF]

I need some help. I referee in a local recreational league - i referee middle school (7&8th grade) girls. It seems that there is one or two girls that always setup in the key when their team is on offense and they dont move. In one game i called 3-second violations about 20-25 times. The coaches & spectators were aplauding me for calling it due to the facts that the girl was just sitting in their & getting all the rebounds. I was then told by the coordinator that the girls mothers called him and he told me to either wait 10 seconds & then call a 3 second violation or dont call it at all. I appealed to the recreation board and they are stumped. Can any one help me? (Sorry for the long post)
