Cash send

I sent myself the voucher using the app because I didn’t have my card with and I did cash send when I go to the ATM it said voucher cannot be redeemed

To be quite honest, this system of yours is very unreliable it says that the voucher has been redeemed when it hasn't, and I am loosing out on money because of this.

I would like somebody to please contact me regarding this matter, because it has left me extremely frustrated, and at this point I'd like to even close my account because this bank is useless!
