Unresolved stop-order debits for my deceased uncle under Policy AL***A2

I claimed for my late uncle in July this year. After initial delays due to AVBOB's system issues and manual processing, the claim was finally paid out. However, AVBOB has continuously debited premiums for my deceased uncle via salary stop order for July, August, and September.I have called their consultants multiple times, only to be given empty promises that the claims department will be notified. Absolutely nothing has been done. I cannot cancel the stop order at my HR office because my father is still covered under this policy, and I cannot risk his policy lapsing. It is completely unacceptable to continue charging premiums for a deceased individual months after the claim has been settled. AVBOB needs to refund my money, stop these ******* deductions, and ensure my father's portion of the policy is safe.
