Debit charges and invalid Digital voucher

1. ABSA charged me R150 for each delayed debit (not reversed). 2. Private Banking contact number which is supposed to be available 24/7 is not answered. 3. Bought a one month digital voucher on ABSA rewards and was issued with an invalid voucher with an expiry date of the same day I bought it. Logged a call which I was promised will take 6-10 days to resolve and still not resolved.
