Unauthorised Outsurance Car Insurance Debit Order

I am very frustrated that Outsurance keeps on deducting (two times a month) a car insurance that I cancelled on the 15th January (Where as my new insurance broker also sent Outsurance a cancellation email on the 16th Jan) When I noticed that they are still deducting I called in and cancelled again on the 31st Jan with a consultant who confirmed that the insurance is cancelled. Last week one of Outsurance Brokers called me to check if everything is okay i got shocked to learn that the car insurance I cancelled in Jan is not cancelled. I then asked him to ensure that it is cancelled, only to find out that this insurance is still not cancelled, Outsurance deducted once again on the 28th Jan. Because they taking monies from an account that does not have funds anymore, every time they deduct the unauthorised deduction, my bank charges me R105.00 for each unpaid transaction. The reason for the cancellation was that Outsurance suprised me with an annual increase of more than a thousand rands for two years.

Remedy Desired:

Can Outsurance please cancel this policy with immediate effect as per my multiple requests in Jan and refund all the unpaid premium penalties in my account. Thanks
