premium tab upgrade purchased

premium tab upgrade purchased but i haven't any in my inventory indicating premium so i can sell on trade, any ideas how i go about initiating the tab. Yes i purchased through microtransactions but POE denies any involvement with these transactions for some reason.
Any help would be appreciated.

What do you mean?

I think I've bought this but I can't remember exactly how it worked. I think it is done randomly on one or multiple of your non-premium tabs, depending how many your purchased.

So have any of your non-premium tabs become premium? If not try restarting game maybe.

Did you purchase the upgrade through the in game shop? Were the points deducted from the account?
