Burleson County Sheriff at 1334 Texas 21, Caldwell, Texas.

This sheriff's office has numerous phone extensions, however, when the non-emergency number is called, nobody ever answers their phone nor do they return calls when a message is left. Are they really that inaccessible except in a real emergency??? And when a person goes to their office in person, rings their buzzer for assistance, it might be well over 15 min. before a response. Is there nobody in the offices during business hours???
