Free Fire Diamond Purchase Blocked – Payment Issue Needs Urgent Fix

Dear Free Fire Team,

I am facing a major issue with purchasing diamonds in Free Fire. I used to buy diamonds without any problems, but now every single card I try is being declined. I have attempted more than five different cards, yet all of them have been rejected.

Previously, I used a specific card for diamond top-ups, but now I keep getting a "Insufficient Balance" error, even though the card has sufficient funds. This keeps happening over and over again.

I have reported this issue multiple times, but I have not received any response or solution. Why is this happening? Please resolve this issue as soon as possible. I am unable to make purchases, and it is extremely frustrating.
