My biggest mistake of all time. The huge lesson, please advise me.

Tonight, I was cleaning a pen I bought a few days ago. A Pineider Forged Carbon. I tried to disassemble the pen to clean it for storage, but twisting the nib caused it to misalign. It was a huge mistake because after "fixing" it back to its original place. it starts egging ink drop when the nib is pressed. I am afraid that it is gonna be a costly mistake as I caused this problem. I emailed the retailer, and Pineider asking whether there is a way to get it fixed.

Please advise me if you have any recommendations or experience that I can use. I am in such a panic right now. I have never had so much regret. Fuck me.
