complain regarding no communication for payment

I have been trying to contact Sanlam via email and telephonically. even laid a complain but no feedback yet. I was a Glacier employee and resigned and my last working date was 31/10/24. I was offered the conversion option for my policies but to date no further contact was made. I tried reaching out numerous times but to no avail and seems like my policies are now going to lapse as i missed 1 month now. I want all my premiums back which ive paid over the past few months while being an employee. I have proof of all my emails aswell of reaching out.
