Refund by the Old Mutual

My name is Catherine Mpungose I have been a loyal member o old mutual for ages I had an investment for education for my grandchild and I decided to cancel it last year July 2020 It was paid fully so but debit order was going through from my account I went to them five times where sometimes their systems were offline and they couldn't scan my document cause of the thickness. finally one the consultant did able to scan them and told the turn around time is ten days ,messages was sent to say your application is in progress and stating that August premium was credited back. My frustration is that why are they not refunding what is due to me, but it was easy for them to deduct it from my account I had to stop my debit order via my bank. their negligence was to stop a debit order when policy was cancelled .the fact that 2 payment were reversed that means they were aware of the transaction and didn't do anything about it. I was not aware about the debit order cause I am used to Old mutual deducting from my account unware that the amount of R350.66 was not supposed to be debited Call Centre you wait for ages due Covid 19 regulations you drive to the branch no help.. I just need my refund because If I didn't notice it would have been deducted forever.
