Cancellation Nightmare

On 18/08/2022 I sent a request to cancel the tracker initially installed on 10/12/2018. I understand there is a 30 day notice period so I expected my last debit to go off on 01/09/2022 for the month of September. On 01/09/2022 I still have no response I send another request to cancel. Still nothing. I purchased another vehicle and decided to remain with Beame. The guy who did my policy confirmed that i would NOT be debited for the old car and the new one and I will only pay R59 at the end of October 2022. I have been debited R170 this month. I want an urgent response.
