********** Activity by Outsurance after cancelling contracting and debit order

We took out insurance for the building in 2017 and with Outsurance since they are linked to FNB. On the 3 June 2020 we wrote an email giving them a months notice to cancel the insurance as we got a quote which was more than 50% better than what we currently paying with Outsurance. A week later I did a call back to their Customer Service number and they responded within a minute thinking that I wanted a quote and on asking for the cancellation department the agent said that if we wrote an email our contract will get cancelled and that the department will call back. Till this day they never called. After reading a lot of bad reviews about how difficult it is to cancel with Outsurance we cancelled the debit order to ensure that money is not debited from the account. To our surprise they still managed to deduct the money this morning despite all this effort. Now we are covered twice for the same thing. Please can you credit our account with the R820 that you debit as this is *****.
