In honor of Jennie: They are rods. Poles are what linemen climb to fix the wires. :hoboy:
As for sending you a new top half, the upper section would have to be fitted to the lower section. There is enough variance from rod to rod to make sending you just the top half infeasible. They will replace the rod, I am told. Never managed to break one (yet).
bring it back, they should replace it in the store where you bought it, GI joes does. I've doen it, otherwise return all and they will replace the whole rod. a good deal, worst case they will charge you shipping.
