Query Refund

can someone please help.. we have an issue that has been going back and forth for more than a month now and no solution. Nedbank transferred money into a standard bank account, and the account is not active so they asked us to go to Standard bank to prove that the account is not active which we did and going forward they promised us that we should give it 7 days and the money would then bounce back to Ned-bank which it didn't until date.

so every time we go back to Ned bank they keep telling us that the problem is with Standard Bank even after having done what they requested us to do.

please can ask that someone please assist us,we are really frustrated...
