Voucher cannot be redeemed

I've sent myself a cashsend but when I tried to withdraw the money,it says voucher cannot be redeemed,I tried 4 different ATMs and a Shoprite and Pep and still get same response. I call them they tell me to keep trying,I tell the agent I already did for 2 days,she says there's nothing she can do,I tell they must rather return the money back to my account,she says that will take 30 days,why am I supposed to wait 30 days for their fault 😡😡
