Get a new rod to use while you do this….
Remove the reel and anything else attached to the rod that wasn’t there when it was bought. determine the direction of the bend and then tape a sinker to the handle down near the end and on the opposite side of the bend and then hang the rod by the tip using a small cup hook to see if the weight of the sinker is enough to straighten the rod. If the angle of the tip top in the hook makes the rod tip torque badly, use a paper clip with one end straightened to go thru the eye and get taped to the rod blank then hang by the remaining loop. You’ll have to play with sinker weight and ideally you’ll want the rod to hang perfectly straight. Now put the hook in a joist in the utility room where it won’t get banged around but where heat from a dryer or water heater is common. Take the rod off the hook every couple weeks and hold it straight up and down like the rod did hanging on the hook. If the rod stays straight, go fishing with it. The rod will straighten with time in that environment even if its got a bad bend.
