Unpaid Excess Amount

On the 19 December 2016 while driving the car I insured with Auto and General (AUDI A5) from a filling station in Bloemfontein, another vehicle reversed into my vehicle and caused a huge damage. The accident was immediately reported to the insurer and the process of fixing my vehicle commenced in January 2017 and was concluded later that month and I paid the required excess amount of R 5 600,00 as per the requirement. Few days after the repairs were concluded, I started to enquire about excess recovery from the third party but there seemed to be no urgency from the insurer to recover the excess amount. To date, I have not heard anything from the insurer.
