Bent Banana Plug

I recently discovered that I have a couple of bent banana plugs. I evidently bent them moving my speakers. I know now I should remove the cables before moving the speakers. I'll just chalk this one up to "live and learn".

Is there any way to carefully straighten them? I guess I need to have them replaced. can I let my local guy do it or do I need to send them back to the manufacturer. Does it in any way affect their value if I use someone local? And no, they don't screw off......I did have enough sense to check that. They are Acoustic Zen cables BTW.
