Very disappointed by Woolworths

I am very much disappointed with Woolworths I’ve emailed them on the 11/09/2025 a request of canceling the comprehensive insurance, they responded on 12/09/2025 by saying I forwarded the email to the wrong department but they have forwarded it to the financial department of which is the right department. I never heard from them since, I don’t know what I must do now but I don’t want this comprehensive anymore they better fix it before they lose a customer.
