We received more than five messages that are restoration was soon. Today we still have no power. We spoke to a representative who described your method of fishing out. Remaining customers without power is truly questionable. It seems you are turfing with other companies who own poles. People are without power. Get real

Excellent. But even more wonderful were the men who did the actual work to repair the leak. They deserve recognition especially the head man.
