Trying for cancel the bond for the last 3months

My house bond was paid out in March2020 the settlement amount was ZAR39691.28 and not aware/ informed that I had to cancel the Nedbank life assurance as well since it was taken from one account, I have been going in and out to the Nedbank branch even calling the contact Centre, no one had the curtesy to advise on the correct protocol of cancellation, Instead I had to pay every month after settling of the bond, the money that not even one of Nedbank consultants was able to explain what was happening, • 30Apr2020 I paid ZAR1781.00 and • 18May2020 I paid ZAR1851.80 (both amounts above as per the NetBank consultant this was the interest accrued after paying off the bond) two interest within 30days just don’t make sense). • 30June2020 ZAR561.88 Debited ((as per the NetBank consultant this was for the life insurance) • 23July2020 ZAR3300,00 deposited on to the bond account, I was told is the balance we owed for the life insurance, which I fail to understand, how does one owe an insurance? The debit order was still active and have more than enough fund in the account why I was requested to direct deposit the funds, As a Nedbank client for years I am disappointed with the service I'm getting, the last consultant I spoke to a consultant at the branch she claimed she was tired and hungry requested us to continue the next day. the only thing I ever wanted was to get the tittle deed, now I don’t know where else to seek for assistance, All I’m looking for is for Nedbank to refund for the above payments mentioned above, back to the same account.
