Unable to purchase RP with TRY in TR server

I currently reside in a European country but play League of Legends on the TR (Turkey) server, where I actively participate. Recently, I attempted to purchase RP. When I open the shop, prices initially appear in Euros. I then click on “country name which appear as hyper link for choosing currency” I click it and the only available option is “Türkiye.” After selecting it, the shop prices change to Turkish Lira, and I proceed with the purchase.

However, every time I complete the payment, I receive an error. I’m not charged, but I also don’t receive any RP. I tried this yesterday 4 times in a row.

Since I’m playing on the TR server, shouldn’t I be able to purchase RP in Turkish Lira, even though I’m located in Europe? Or is there a technical issue preventing this?

I have contacted the support, they came back after 1 day, asking for account information such as username etc. since i used a different email to contact them other than my account. I sent them the info requested, now waiting for their response.
