Cash send USELESS

I sent two people cash send on the 29 and 31 August when they tried redeeming the vouchers it says voucher cannot be redeemed at a Capitec ATM the other person tried at Shoprite at it said the same thing now Capitec customer care is telling me to wait 30 days so I must be inconvenienced with my own money.Why did you introduce cash send if your own systems are failing clients.If it cannot be redeemed at a Capitec ATM what makes you think it will be redeemed at Shoprite etc Your service is pathetic I am not going to wait 30 days I want my money reversed back into my account
