Customer & supplier Return

Dear All

in old system creating cusotmer return and supplier return was easy. Now with new system we have to add negative before figure. Till that it is fine. Now when we either receive refund from supplier or we pay customer refund we can see under supplier return or customer return. 
When we see in unallocated transactions and try and match it, we cannot see that entry. So not sure how we match it.

When i click on customer return we see refund or apply ...not sure how it works.

i tried to call MYOB twice and they said they will call me but no one called. Me. Can youone help
