Capitec -Cash send voucher fail

I did a cash send and once i tried to redeem the voucher the machine said that there was an issue with trying to redeem the voucher. On my app it showed that the voucher has been redeemed , however i did not receive any money .I went to Gardens centre the next day to try again and it showed that the voucher could not be redeemed i then went into Capitec and got a incident number .I had to wait 24 hours for a phone call, obviously no one called .I then contacted capitec on whatsapp and was told that the investigation was rejected .I am speechless as i dont know what else to do .Or who to contact as the cash send was unsuccessful and i am still waiting on Capitec to assist . This is the first time i have experienced this horrible service from Capitec .
