Microtransaction

Purchased cosmetic skill override on pathofexile.com for detonate dead. It didn't show bought so clicked again several times. It took my coins multiple times and I am down multiple amounts of coins and still shows buy for cosmetic. I just want the excess coins back and to make sure I got the cosmetic. I believe I had 1100 before purchase and it should've cost about 95. I now have 895 which is a large loss.
