failure to confirm cancelation

Good Day<br> <br> i called Hollard vehicle insurance on 2 occassions to cancel my insurance. The consultants did not confirm if the debit order has been canceled and did not send me proof of cancelation as they said. My concern is that they will debit me in error and cause problems on my side.<br> <br> Could Hollard please send me confirmation that my insurance has been cancelled and that i will not be debited by them as i have taken up insurance elsewhere.<br> <br> Regards<br> Melissa
