Incompetency by Sanlam sky

Late November 2021 Sanlam sky sent me a message as there client that in December they will be debating my monthly premium early because most companies will paying employees early. Then they sent an SmS to say they will be debating on the 15 of December 2021 I did not have an issue with that because I still had money in the bank. On the 15 December they did not debt and I made a call to arrange again with them since I was payed on 17 December 2021 I requested them to debt on the 28 December nothing happened. Today it the 29 when I call them they are now saying this request will take 5 working days mind you my normal debt order goes off on the 30th of every month. Now they are saying it not possible for them to debt there incompetency is inconveniencing me now.
