Unhappy with Old Mutual Rewards

I have a funeral policy with old mutual. Every month Old Mutual allocate a certain percentage of rewards to you which you can use to buy at certain shops. I was awarded a family bonus which was reversed the following month because their system was not updated. They only told me after I enquired about the reversal and Zubayr Limalia at sent me an email. "We processed a points reversal on 28 February 2022 due to the fact that the January 2022 points allocation processed on your Family Funeral plan premiums incorrectly included the Family First bonus points which should have stopped as at 31 December 2021. We will process your updated January 2022 points excluding the Family First bonus points in due course." So this is bad service to allocate and then reverse points because the system was not updated. If I go to a shop and there is a price on the shelve for a certain item. I will pay that price even if the promotion is finish.
