Debit for policy that I don't have

I'm not a client of clientele but i have had 3 deduction made from my bank account. I contacted them in early august 2021 to ask them to refund me and cancel this policy that i have not agree to in the first place, policy was on someone else's name only banking details was mine. they cancelled the policy. however end of august another deduction was made. i called them and they said previous policy was cancelled. this is a new policy. they said they will cancelled it. I was refunded for the two deductions. September another deduction goes of. Now I'm tired, clearly something is wrong on your side, I need to phone every month to fix this. who pays for my airtime. I still need my refund and a full explanation on how this happened in the first place.
