Debit for inactive policy

When my husband passed away in Sept 2021, our funeral policy lapsed due to no funds in the account, however - Old Mutual is still deducting the premium off my account even though there is no active policy. My broker has been up and down with this. She told me that they refunded me with no proof of it and yet this month they deducted again. This is horrible service as this has been going on for too long
