Bad customer service

I am terribly disappointed in the service from Naked insurance. I took this insurance on the 10th selected my debit date and received confirmation of everything. My pay day/debit comes they only debit R311 come today 3/11/2023 they want to debit R1964 from my account.

When I ask Paballo all I get is Automated messages about changing my debit date again on the app even after I mentioned I cannot do that as it requires me to an amount way over my premium for my policy. I now have to pay oner R800 more on the agreed premium on my policy document. Can someone call me to rectify this otherwise please cancel my insurance.
