Woolworths Insurance - PLEASE respond to my cancellation request from 28 Dec 2018!!

I have been trying to cancel my home insurance since 28 December 2018 with 1 response to my 7 emails to date about it. I have escalated it to ********** with a response coming from Nadia on 16 January 2019. Since then nothing. I have had to resort to dealing with my bank to try to stop the debit order coming off again at the end of this month. Woolworths, a response to my emails and a refund for January would be appreciated.
