Don't want to have to remove the positive trust from a while ago 
If your feedback in the past is due to the successful deal then there’s no need to delete it because it’s backed by successful transactions worthy of positive feedback. Let the new negative feed do their work on giving warning to other user that will potentially have deals with the user. That’s why you should only give positive trust to user that shows trust worthy act and he deserves that during the time of your deal.
I read every comment on this thread, Believe me no one is in my position and i hope no one will be in my situation. I was silly enough not to secure my accounts and my phone to make it easier to reach out my apps quicker and i never expected to get robbed like that. That guy could reach to my exchange and my other wallets too and I am trying to get in touch with the support to find out who did that and to even try to track him out. Anyways I will reach the op once I get the hella out of this hell and I will try to get the money to compensate him ofc i have a big loss already and ofc I am not a scammer and I do not like to see someone get scammed and I know many of you has dealt with me for years and they know that I am not a scammer.
This is still vague excuse because how come a hacker can login your exchange account without knowing your password? Does your phone doesn’t have any security installed because the first thing thief will do on stolen gadget is to factory reset it to avoid being traced back by the owner.
There’s a feature on Android and Iphone that you can detect your device location when connected in the internet.
