Shop loading/lagging and buying same Currency stash tab multiple times. PLease help

Hello,

I bought the "Path of Exile 2 - Path of Exile 2 Early Access Supporter Pack" for €27.75. Now I've played through the first 3 acts and I'm thrilled.
The Suppoert Pack contains 300 coins. In the shop under Stahs Tabs I wanted to buy the Currency stash tab for 75 coins. But something seems to have gone wrong during the purchase.
When I bought it, I got a loading bar at the bottom right and after a while the message that the action could not be carried out.
Unfortunately I repeated this 3-4 times with always the same result. Nothing was deducted from my 300 starting coins and unfortunately I didn't have a currency stash tab either.
After I played some more, I noticed that my 300 coins were suddenly gone and I now have the Currency stash tab 4 times...

Is it possible to reverse this?
