Lowiq Scammed me!

i cannot link his profile for it seems it was taken down. but it is @Lowiq
so, the trade was 600m for a maxed main account, with a middleman: Yirru.
We did the trade in a discord chat with him, me, and yirru. Yirru received the cash from me to middleman the trade, along with the fee for it. I did so. lowiq then proceeded to give me the details for the account. I had asked if it was being recovered after, and he said no. I received the details, and changed them to my own, even with a authenticator activated. So after a few days of playing on the account, I went to log in the next day, to find it saying the password is wrong. so I went online to the osrs site, and found it saying wrong. I started to do a recovery, and there it was. linked back to his own personal email. I have tried to contact lowiq about it, and also asked yirru what I can do as well.
I was scammed for a total of : 600m + the account traded.
