Contract cancelled and still *****ing money

My contract was cancelled on the 20th October 2015. See email: And MTN is still *****ing money from my account every month. This is the worst company to work with. Called the call center, spoke to Ms Mafutha. It took four times for her to correctly write down my contact number.
