Policies: Debit orders

I have 2 funeral policies with Sanlamsky/Momentum last month on the month on the 5th Of May 2021 I paid for these policies as follows: Pol no ***0 an amount of R250.00 ( to catch up with the arrears Pol. no. ***8 an amount of R50.00 which is my normal monthly premium. I was given these figures one of their call center agents. After I requested them to debit my account on the 5th of June 2021. ( This is my normal debit order date) They fid not do so on the 5th as it was on a Saturday therefore I expected them to debit today, nothing came forth. I then called them just now and spoke to their consultants namely Kylen & Ntombi. I was put on hold for a long time, thereafter I was informed that they cannot fi d my policy numbers even if they use my ID number The phone calls lasted for almost an hour but no resolution was arrived at. If they cannot trace my policies with my ID number, Names and Surname, how does their system work. Ultimately they will tel me that my policies lapsed due to none payment of premiums????? Whose fault will that be??? There is enough money in my bank account therefore I don't know why the de it order never went through. Will they kindly advise urgently please.
