ABSA Rewards Calculated Wrong Again and Again

Just got paid my ABSA rewards on 1 March 2019. This month I got paid R78. Yes R78. I earn more than that in a week via Sasol only.

Yet again the calculations are incorrect. I shouldn't be surprised as its an ongoing thing every month for the last few months. I log a call, they recalculate, pay the difference mid of the month, I request a transaction calculation sheet, I get it a week later.

ABSA need to automate the rewards system. I'm sure my new savings account and the R250 paid into it monthly hasn't been included. The tiering is calculating incorrectly every single month. and as a Private Bank client, I shouldn't need to check if it was calculated correctly. Clearly there is either *********** staff or the processes are flawed. ABSA you need to automate the system which I believe should be regulated by the South African Reserve Bank. If ICASA can regulate ISPs why cant SARB not regulate the banks rewards systems?
