Shocking service from Absa Home Insurance

We have had home insurance with Absa for over 30 years. We sold our house and the transfer went through on 13/9/2022. I contacted their offices on the same day and was told that we would have a refund within 3 working days. After numerous calls, emails etc. We still haven't been refunded. In the 30 years plus, we have paid in excess of R550 000 insurance. You'd expect a refund of +-R1000 to be paid without delay.
