AIGSA insurance cancellation

Apologies as AIG life was the only business listed, I want to complain about AIGSA short term insurance where I cancelled a year ago yet they keeping deducting from my account. I have enough cancellation letters, they also reinstated my profile and said that there wont be anymore debit orders as the same when they cancelled last year. This whole up and down go to the bank to do a reversal is costing time and effort as I have already lost my patience. And its not any little amount. Its amiunts ranging between R700 - R1300, if i could give a rating the way I could , it will be a - 100 star out of 5 because of this issue being a monthly thing for the past year and
