User try harms me and support does nothing

Please see this.

This user is chasing me for a long time, in time, copies everything from me, persecutes me, creates users fakes to negative me, every time I put something to sale he puts the same item at cost price just to harm me seconds later, Copies all my promotions and even encourages others to harm me as in the image below. I’ve been reporting this for months and the gameflip does nothing. Look at the comment now, he’s trying to argue against me by encouraging other sellers against me. Honestly, it has gone overboard, I am a serious seller and I am going to seek my legal rights against this type of abuse.

Hey, I think we are already discussing this case via PM.

Thus I’ll close this topic, thank you.
