You mistakenly released the coin but later you noticed that the money remain 1000 naira? Or you know but you just let it be like that as you think it is little amount of money?
I looked at it the credit notification and saw that it was missing 1000. I deliberately clicked on release coin because that day I was in a hurry. The trader was lucky that was a good day for me. Next time, I will not let it slide.
You should have though the vendor a lesson by intentionally not releasing the coin then go ahead to do so whatever you are willing to do with the money, if the vendor keeps calling, then as him to complete your payment or else you report him to Bybit, the vendor will have to beg you and claimed that it was a mistake.
If people like you keep letting this slid, the vendors will keep repeating the same thing, but a report that might ban him/her for a while will thought some lessons that doing such thing is not good.
I do refer to such vendors as Almajiri vendors because they are begging for money d spite the money they are making.
