Worse service from Safrican

An incorrect premium was debited on my account and I called in to have it rectified and submitted a request for a refund on the 18th of October 2024. I have been sent back and forth when I do a follow-up. I sent an email to their supervisor named Andrew and their complaints department, to this date, I have not received any response from them. Worse serviced ever. It is a huge concern as I have covered my entire famiy with them.
