Very Disapointed and Angry

I took out a loan last year feb 2017 with Direct Axis for 24 months, they told me that I can only get the loan if I have life insurance or if they (Directaxis) take a life insurance out on my behalf until I settle my account so that if something happened to me then they will be covered, I then settle may account in full in may 2017 of which to my knowledge I owe Direct Axis nothing at all and that nothing will be debited from my account. last week I saw on my bank statement that theres a amount of R105.45 which is debit from my account since after I settled my account up till now. Direct axis call centre guys send me to different department and they send me to the insurance company in order to resolve this however I had a agreement with Direct axis regarding my loan of whch settle my account last year and of which Direct axis was suppose to cancel that seing that I settled my account and I would like for this past 14 months that amount was debit to be refunded back to me bt then no one can help and they keep on sending me around to different departments.
