Support, recovery tests only make things worse, more likely to get an account locked and cause confusion and false feeling of safety.
Also when people buy an account and want to use a middleman for the purchase is pure nonsense (unless the account is being resold and the reseller is not trusted while the original owner is) as you shouldn't even be buying an account in the first place if you don't feel safe enough to go through without a middleman. In the end it will most likely be that you lost the account + the middleman fee (if any).
