If you're playing on Steam, submit a refund request for whichever Year of the Prophecy edition you bought, pick "multiplayer not working" and put "Cannot access the content I paid for and play the game anymore due to Bungie restricting access in my entire region and the resulting Tapir error codes". They issued a full refund for me in a matter of hours. If for some reason they deny your request, ask to escalate and keep trying. It's clear that asking questions and trying to do this the nice way is met with ignorance and automated non-answers. So start speaking the language they do understand - money. Vote with your wallets:) Plenty of other great games out there that don't treat you like your money is good enough but you aren't.
