USER TRYING TO SET ME UP

Short explanation, this user contacted me and sold me some GP, he went first I payed.
I got banned for botting.. I wanted to stake buy another 200m and get banned this time for RWT. I ask him to sell me another 200m he says no because hes afraid of a ban I must buy more (I looked around the market for another 200m and couldn't find anybody with a good rate or that accepted Zelle so I went to the bank and deposited enough to buy 750m, I come back he trades me(declines, declines shows me junk accepts puts money up since its 750m and asks me to confirm I do he goes 2nd screen, declines, trades again.. and he starts asking for money..)
I didnt record anything seeing as he was going first and I didnt see how he was going to scam me.. never thought this to be a tactic.

I can provide screenshots of the convo but its all he said she said.. but I can provide proof he sold me 200m twice and no problems

 

it was kind of hard to pick what to screenshot, I asked him for proof of the trade because he claimed he had me on screen record..
he was trading junk (I accepted because I had assumed he wanted me to trade him junk idk I got banned twice so this was kind of weird to me thats why I didnt stop the trade)
