Worst experience i ve ever had in my 130+ Transactions all the time.

First,i wanna tell how bad experience i got by trading with this guy,he bought my listing off,i delivered the account which is perfectly working fine on my side,i checked everything before i deliver the account to the buyer,after that,buyer had logged into the account and changed everything( passwords) etc,yep still appears normal until he said he cant play any matches on my account,saying the account got 'shadowbanned' which he doesnt even really know how it works,i slammed tons of evidence of people getting shadow banned to him,talked about how does shadow bans work etc,but seems like he refused to read and keep flamming me,even takes out a lawyer and says they are gonna talk,bullshet,he said shadowban can only happens if someone plays a game and get banned,which was NOT true,shadowban can happens in any situation like logging in in 2 different location too fast and IW/ACTIVISION thinks you may be fishy and put you in queue to investigate,Now,If you are a seller,How would u feel if your account which is working perfectly sold,you delivered,buyer broke the account,and assumming that you are the one which broke the account,would you take back a broken account,in the whole conversation with the buyer,On other hand,He added me on discord,Asked for bargain but i clearly stated that i doesnt takes any bargain,which already proves he doesnt even read,still bargaining,i refused,Scolded me AIDS and got directly blocked by me on discord.After 2 days he bought my listing due to his 'good human being',what he did is broke your account,wants a refund and run,just becareful on trading with those guys on playerup,people who bargains with you will just gives you a loads of problems after dealing with them,I do not recommend dealing with those guys,just,dont.
