I Got a Poor Feedback Without a Reason

Someone gave me a poor feedback without a reason 1 day ago. He bought my “Steam Game Bundle” and we don’t even contact with him. He just gave a poor feedback. I need admins’ help. I want you to delete that poor feedback please ;( I didn’t have a poor feedback until yesterday. His name is Dadi btw. And here is my invite code : 5E22NF

As i checked your account, this rating was removed already.

If you need any further help, please PM me.

Thanks!
