Appalling service as usual

I went to request for the bellville branch to update my new bank details they advised they have done so, my policy did not deduct for this month and a similar issue occurred last year and I was told that I am missing one premium this is no fault of mine it’s their flawed system and they failed to tell me who will then pay for that outstanding month! I unfortunately not an employee of Avbob if I was then I would ensure would tell my customers if we have any issues with the billing system for them to at least know but this is not the case with you guys kindly amend my policy as a matter of urgency there is always money on my account this should not be a problem
