Didn't uphold his part of the deal and ultimately recalled his account

Part of the agreement was that he provide after-sale support. Due to the nature of how susceptible to security checks BDO accounts are, it's pretty important to have after-sale support. I requested it as part of the sale and the seller agreed. He either deleted his discord or blocked me on discord 5 days after the transaction. He didn't respond to the phone calls or text messages that were sent to the number he provided me with. He even ignored emails I sent to his PAYPAL email. Eventually, the account was recalled but the seller denies recalling the account saying "I can't recall the account if I don't know what email you changed it to!" This isn't how things work for BDO accounts, or for any online game accounts for that matter.
