Capitec Bank

I went to these small screen Capitec ATM and withdrew R1000.00 but only R600.00 was dispensed then withdrew another R200.00 and it came through meaning there was no cash stuck in the dispenser, contacted the bank immediately and they advised the matter would be investigated, Ten days later still without any correspondence from the bank I made a follow up call and was advised that the matter was unsuccessful as the ATM dispensed R1000.00, what mockery is this.
