Follow up on Policy issue since 27 March 2023

I am an issue with my 5 existing funeral policies with standard bank. On 14 October 2022 I reversed my premiums after that the policy was no longer debiting. I called the bank and was informed that I have to make a new arrangement. On 13 February 2023 I called the department and had asked that I have an arrangement for all the missed premiums to be debited on the last day of the month 28 February 2023. On the 28 Its shows that policies did debit but shortly returned to my account with reason not provided. I called on Saturday 25 February 2023 and was told department is closed , I should leave my contact details and the bank will call me back. I have not recived the call. i called the bank again this morning 27 February 2027 spoke to a Prudence Mugwevu who I sent mybank statement to show that i had arrangemnt for debit to go off but returned as "not provided for". She suggested that i call general banking to query why its not debiting if I had fund. I called general banking Spoke to Tintswalo who advised that they had a system issue hence the premiums where returned. This means that I have not paid for another month from the month of October despite me making an arrangement for all premiums to be paid. Should anything happen to me or my family I would be in a real predicament. I am so displeased with service from this bank honestly as I have issues with them every month. I so disheartening and takes alot out of a person. why should I now have to pay again and delay my policy yet again by another month.
