Cancelled Retirement annuity but still debiting my account.

I cancelled the retirement annuity but the still debited my account. Went to the branch again Carnival mall asked for the manager and they checked on the system and they said the policy has been cancelled they don’t know how it still debited. I requested a refund which was done to this day I haven’t received the money and again the debited my account this month.

I can’t pay some of my debts because they keep debit and when I try to reverse from my band ABSA they say they can’t because it’s not a debit order but a debit cheque. I don’t know how to solve this problem please assist. I also sent a complain to Old Mutual but no respond to this day and it’s been a month or longer no. When I call I can’t get through I stay on the queue for more than an hour until I drop the phone, not sure if the decide not to answer cos they can see my number.
