Wrong debit order dates

Goodday. We have an insurance policy with miway. The first debit order went of the 30th Nov. As well as in December, it went of on the last day of the month as requested. Suddenly in January,the debit order went of the 24th of Jan 2024. I phoned them and they explained it was a system fault and they will correct the date to the end of the month. I believed them. February it suddenly went of on the 23rd of February. Again we phoned and they told us, it is because they want to make sure they get the money. Really!!!!!!! This is the worst customer care I have experienced. I only get paid the end of the month,but it seems to me they make they're own debit order dates. And all that we get is excuses. If this is not fixed this month,I will cancel this policy.
