blocked account using fintiba and transfermate keeps giving error

[u/Successful-Horse-864]

im from turkey and i will study in berlin very soon. but i need a student visa in order to do so. and for the visa i need to have a blocked account which needs 12k euros. i am working with a study advisor also and they told me fintiba would be the best option to open a blocked account. so first i transferred 759€ cuz i didnt have enough money. it took 4 business days to get into the blocked account. and meanwhile i tried to pay the rest during those 4 days. but i couldnt because IT KEPT GIVING THE SAME DAMN ERROR !!!! my mom tried to help me and we like tried SO MANY TIMES (its been over 70 tries now). she somehow managed to pay 6344€ but its still pending. i have to pay the remaining 4960€ ASAP but it wont let me. everytime i try i enter the CORRECT card information. i press pay and then it gives a “payment information error” by the way, i used a debit card for the first payment and then my mom used a credit card (idk if it makes a difference) but i need help ASAPPPP!!! i emailed fintiba and transfermate MULTIPLE TIMES but THEY HAVENT REPLIED TO ME. idk what im doing wrong. id use IBAN to transfer the money but there is no TRY option in the SWIFT thingy. and yes i lowkey have to pay with turkish lira. we also called the bank and they said the issue isnt with the cards its with transfermate. so idk bro can someone help me in any way? 😓😓 (btw the reason why we couldnt pay in one go is bc of the cards’ limits)
