Wrongful Additional insurance debits

For the past few months my acc has been debited for an amount of R132, When I went to the bank to find out who is debiting my acc I was told its Innovation Group and I was given the number that I can call and settle this issue. When I called Innovation group the 1st time the consultant told me that they can't see a debit order instruction that I am talking about. I was then transferred to another department where I didn't get help. I called again querying the same issue and again the agent told me that they do not have a record of the debit instruction that I am referring to and transferred me to the credit shortfall department, where I was told that they too do not have a record of the debit order that I am referring to. I was then transferred to a department that deals with financing vehicle and they had no record of me being a client of theirs. My account has been debited for roughly 5 months and i can't stop this debit order because I keep getting transferred to different departments
