Capitec cash send disappointment

After sending a much needed R500 cash send on 25/06/2020 to a family member,he got a respond saying "voucher cannot be redeemed". Capitec has been my "office" since then. I am just told that they are working on the problem. That can't be put on the table to eat. Silverwater Crossing Pretoria branch has tried to assist me all this time till late this afternoon. They got the same response from the technical department. Extremely disappointed and frustrated.
