To be frank, your behavior during that entire interaction with your seller was so abhorrent that it absolutely warranted a permanent ban (which you are welcome to pardon for). The seller was generous in selling you the account and giving you time to pay for it. When you did not meet that deadline he got upset, which is understandable. What is not understandable is how YOU reacted, which was to threaten to have the account banned. It was petty, it was childish, and above all scummy beyond belief.
There was a lot said but I think this sums it up best:
"i am reporting the account for permanent ban regardless of any sythe report or outcome...if the report isn't closed within 5 minutes i'm perm banning your rs account for rwt as well as you not getting paid even if they perm ban me on sythe etc i'm leaving sythe soon and don't care"
You are welcome to pardon for this in 3 months from the date of your ban
