I Can’t Complete High-Value UC Purchase on Midasbuy Due to Unipin Payment Error

I’ve used Unipin via Midasbuy many times in the past without any issues. But now, every time I try to make a purchase—even with the same email and phone number I’ve used before—I keep getting an error message just like the one shown in the screenshot.

I urgently need to load a high amount of UC, but the system won’t let me complete the transaction. I’ve tried everything: different devices, emails, and numbers, yet nothing works. This issue is stopping me from making an important purchase.

Midasbuy support, I need you to fix this immediately. Your platform is currently preventing me from spending money, and the delay is costing me time and in-game opportunities. Please solve this now so I can complete my UC purchase without further hassle.
