Deceased policy not found

My husband died few years ago and had car insurance with dial direct and upon assessing his bank statement I found out dial direct was debiting 3 different products so I called dial direct to ask for the insurance schedule to see why he was debited 3 different amounts and theu said they cannot find his policy with the provided policy numbers and his ID number and they suggested I give them more information and I already attached screenshoot of the bank statement so I asked what kind of information is required and no answer. Also when u contact them telephonically they have AI answering their calls which is unprofessional because that thing only speaks English while South African has 11 official languages and it only ask u what it was programed to do and nothing else so it's so inconvenient to waste our time speaking to a machine.
