Let's use an example: You started a transaction for 100 USDT for NGN 70,000, but you sent 105 USDT.
In this case, you have two options:
Request a refund of the overpaid amount (5 USDT) It will be processed within 48 hours.
Process the overpaid amount (105 USDT). This means you'll get full value for 105 USDT.
