complaint

I posted in trade chat about buying enderpearls. MrCoolTrent replied and offered them to me for 5k each. I refused. He then went down to 1k each. I refused again and offered $500 each. He agreed and said he had 5. I met him at Rising spawn and paid him the 2500. he disappeared. Then reappeared and gave me 5 potatoes.

then all he would say is that he would sell me enderpearls for $1000 each.

I am attaching the screenshots
