Issue with account & linked account

Hi, I am playing poe2 and was playing poe1 before. When trying to activate poe2, I thought I had to link to my steam account and this link my main account to an apparently existing and old account with 1 templar lvl 1 (must have tried and stopped at the time).

My issue : somehow, poe2 was created on the steam account instead of my main account ! Moreover, the 300 coins which were on my main account just got transferred to that linked account where I have no character on poe1. In addition, i am pretty sure my poe2 characters were on my main account and somehow got transferred to that steam account, hence why i don't see the coins anymore. Weird

In short : it's a mess. Can someone from PoE just merge my two accounts or delete the old account and transfer both coins, cosmetics and poe2 characters back to my original poe1 account with 24 characters ?
