Hollard Pay As You Drive is Not accessible for claims

If I had zero on star I would, my dad (69 yr old) has an old policy, dating back to 2017 with Hollard: Hollard Pay As You Drive and he had an incident on Tuesday. We are battling to get connected to the correct person to log a claim with. Hollard claims the policy was transferred to Dot.Sure, Dot.Sure said there is nothing on their side except an old pet one which was cancelled. He is paying R532.99 a month for this policy and yet no one is available to assist or log a claim with. We have given them his ID, all the reference numbers we have but nothing on the system, yet money is coming out of his bank account every month. Somebody out there, pls help the old man
