Furious and very disappointed

I opened an life insurance with these ******, I then lost my job few days later I asked them to cancel the policy as I cannot manage anymore they didn't instead they reduced the premium and continued to debit further creating a minus on my account, I have sent numerous emails to cancel the account they refuse, on the 7th of April 2025 they deducted the money I had received to buy some food now they refuse to refund me and close the account
