Cash send not redeemable

Good day

I sent one of my employees money via cash send on the 2nd of July he was unable to to retrieve it as the slip from the Atm kept on saying unredeemable. I went to all capitec branches from Bronkhorstspruit to Pretoria. I have called twice and no one can seem to help me. Please my employee is in desperate need of that money. This has caused a serious inconvenience not only to him but me also. This is the sms I got
