Still deducting after cancellation request

Dear Absa,

On the 15th of August 2017 I visited one of your branches at Festival Mall in Kempton Park to cancel the life insurance on my personal loan and credit card. Both these accounts have a minimal amount to settle them however for example what you are charging me for the life insurance is half of my monthly instalment of the personal loan. Firstly I couldn’t cancel this by only making contact I had to go into a branch to do so. The person at enquiries then sent emails to cancel credit life insurance for both accounts. However since then I have paid this morning my second instalment after I personally went to cancel it at one of your branches. Please could you assist to cancel it with immediate effect and pay back the instalment that you have deducted after my request to cancel it? Regards, FJ du Preez
