İş Bank Digital Banking Blocked In South Korea - Need Urgent Access To Funds!

I am in South Korea for language studies, and I cannot access the digital or online banking services of İş Bank, which is my only bank. Before coming here, I specifically asked whether there would be any problems abroad, but about a month after arriving, I lost access. All my school expenses, rent, and savings are in İş Bank, and I only have an İş Bank card. I was told that to reactivate digital banking, I need to go to a branch 10,000 kilometers away, but I still have a month before returning. I called customer service and explained my situation; they sent me a reference number by email. However, when I try to follow up on my complaint, I can no longer view the result on the website (I could see it on the first day). Should I not have trusted İş Bank abroad? I urgently need a solution. Reference number: ISBN25101717019.
