find transaction in bank feed not working

1st times on here currently using account right

in bank feeds when transactions match correctly all i do is press the green approve and we are all good and when it doesnt i simply press find transaction and it comes up most of the time now this is no longer occuring 

have i missed something 

these transactions are in the bank register and havent been reconciled 

have spent hours on hold to myob the last few days but no one is answering and im waiting 40 to 50 minutes any help much appreciated

thanks
