Can't sell my Matic back to euro

I decided to try Binance just because I wanted to buy some Polygon Matic on there, well it has been a complete nightmare. When the price started dropping I just could not sell it back to euro, somehow I can only choose Australian dollars!!!! WTF now I'm done with Binance and I just want to sell the rest of my Matic and send the rest of my money back to my bank account. Does anyone have had similar issues and or do you know how I can do this? I'm DONE with Binance.
