As I post I can verify that all accounts I sell are working at the time of transfer, I do not sell vac banned accounts, and I do not sell non working IDs, I give 24 hours in which I'll accept shannigans, but past that it's clearly stated "no refunds"
I run a simple, and straight forward shop, and unfortunately I don't have the time, nor money to replace every single account that turns for the worse. That's the black market.
