Poor Service and unfair deduction.

Poor Service and unfair deduction. I had an vehicle account with Absa. I decided to pay it off. I then called the bank for settlement amount which they gave me. I paid it on the 11th of Feb on the 25th they deducted R691. 57 for the car insurance they took on my behalf without my consent. I phoned for that refund they refused to give back the refund. I then instructed them to cancel the policy as I was now the owner of the car. They told me it will automatically cancel as it is paid off. To my surprise 2day the policy deducted again and they have now deducted R767. 41.I haven't even received my logbook they promised to post 5 days after I paid off the car which was the 11th of Feb. The person called Kubashnee who works for Absa is the one who used to call me time and again for non payment now that I have paid the car off she is very quite and unhelpful her number is ***.Your assistance in the matter will be highly appreciated thanx
