Cash send voucher theft

I’m afraid Capitec has now started a new ****, which is not dispensing cash send vouchers. Today, I went to go retrieve a cash send (sent by myself) and I was met with an error saying it could not be processed. I checked my app to see if perhaps the voucher number was incorrect and to my surprise, it said it was redeemed! I immediately called Capitec and informed them of this and I was told it was going to be investigated. 2 hours later, the outcome is that money was dispensed And my case was closed?? How??? By who???? It seems Capitec does not investigate these *****ulent transactions and is quick to close cases!
