Hollard Funeral Policy Cancellation

I have followed Hollard Funeral Insurance cancellation process as stated on their website. I have submitted yet another cancellation form to them today, the first was sent on 19 April 2023. I have not heard from a agent to cancel my policy. Only receive emails stating that an agent will call me in 2 days and hear nothing further. Why is it take so long? My bank account is always a minus due to failed debit orders from Hollard. Should cancellation requests not be tended to immediately? I hope this review is seen. I am not happy, this is bad service.
