Many people have placed orders, and the moment of inserting the pin is when purchases are made in order. It is better to directly exchange in the wallet after inserting the pin.

What kind of operation is this from the platform? Clearly, it was set up in advance on the 6th, so why was there no transaction when the needle was inserted on the evening of the 7th? Who do I talk to about this? Does the platform have any responsibility? I would greatly appreciate comments from all the experts!
