Absa Rewards - No Partner Earn allocated on Dischem Transactions

I have been calling Absa Rewards every month from 1 September 2020 to 1 February 2021 regarding not being allocated the correct reward percentage on Dischem transactions. Each month the calculation is done manually often taking more than a week for the reward to appear in my rewards account. I requested from my initial call on 1 September 2020, that a consultant from the Rewards department reviews my reward statement every month to check if the correct reward rates are being allocated and also e-mail my rewards statement to me every month. This however is not being done and I am forced to call Absa Rewards customer services to point out transactions where I have not earned the correct partner earn reward rate. On my last call on 1 February 2021 I requested to speak to a manager in order to have a permanent resolution to my problem, and I was told that a manager would call me before the end of the business on that date. I have still not received a call from the manager. If the rewards system is not functioning as was intended, why is Absa Rewards not putting the fixes in place but letting this issue carry on for months and frustrating customers who simply expect the services that Absa is offering?
