You reached out to support, their response confirmed the account was not pulled, which only leaves one option, it was banned.
It is not logical that you place bans on me, it couldve been banned for anything you said during the week you had the account, using stolen cards/redeeming suspicious nitro, which would also explain the refunds, or simply for breaking discord TOS (buying an account)

Also regarding the OGO statement, you found his phone number from an old email in the inbox which could easily be faked on outlook hence why I asked for timestamps of the conversation you had with him, you refused to provide this. We couldve reached an agreement if we solved this privately however any questions im happy to answer - I am not here to scam or take advantage of anyone and I hope no one gets that picture of me.

This guy is also in general a very suspicious user, he has been trying to sell me his hypesquad events account for ages for a very low price, however the catch is that the OGE is yahoo, anyone who knows about this is that these accounts are NOT safe, I would not be surprised if he faked any messages w OGO or anything like that, but will let staff handle it. https://imgur.com/a/P56K4yr
