Debit order not being deducted on agreed date

Good Day I took out funeral cover on 24 July 2020 at the Capitec Branch in N1 City. I asked for the debit order to be deducted from my account on the 01st of every month. The first amount was deducted on 28 August 2020, and I contacted the call centre to enquire why it had not gone off on the date which I stated and signed for on the contract. The consultant said it was a mistake but assured me that going forward, the debit order would be deducted on the 01st of every month. BUT! Once again the debit order has gone off yesterday, 28 September 2020! I am very unhappy. Why has this not been corrected? It states on the contract that deductions will be made 01st of every month! I signed for it to be deducted from my account on the 01st of every month. Can someone please advise what is going on???
