Double debit

I’m utterly disappointed and upset. I have a policy with you I direct and the agent promised to cancel my insurance policy with the other institution. However, that was never done. I’m being double debit for my car for R4000 per month since August during a pandemic which affects people financially and ABSA being a financial institution is utterly giving poor services. I’ve called several times and can’t get hold of the cancellation department to cancel my policy and get my refund back for the past 3 months.
