Problem With Woopayments

Everytime the customers orders keep getting cancelled, also there is some discrepancy in the payouts. It is as if the system does as it desires, it accepts some payments while cancels others blatantly.
customers keep trying, but it just keeps on rejecting. can you also check the if the apple pay works, someone tried paying with it and it didnt work as well
In 22transactions $3,244.55 total $174.90 fees $3,069.65 net, but under the deposits section it shows $2,768.50.
why is it so?
