i trust you didnt lift it from the ground
if it was at height, allways add sections on whilst pushing it up the wall ( if you get what i mean )
is it fixable ? ? ? ? make the cut cleaner and slide the thinner but inside the thicker bit, you will see how much join you have, slide it back out, whack some super glue on it and slide it back inside and it will be strong, my Zensorflex has been repaired like this twice now, yes you lose 9 " of pole, but it still works fine
