Look, man, I completely understand your problem. I would be furious if the same thing happened to me, especially because you did follow all the instructions and everything seems 100% correct here.
But this really has nothing to do with ETN or their team. This is solely Cryptopia's problem. The link you provided proves you that everything is 100% good on ETN side and that there's no a single reason that ETN is not showing up on that address (I assume you checked like 100 times already that both the address and payment id are correct).
