Third party demanding excess money , what happened to comprehensive cover

Good day , On 9 September 2021, i was involved in a car accident which also resulted in third party damages. I registered my claim the same day and also provided the information of the third party whose company car needed to be repaired. My claim was approved and my car was fixed and I payed my excess, the process was very easy and fast. During the process I asked how will the third party be assisted, the consultant that was assisting me said he had forwarded the information to the relevant department and he will be in contact with the third party so that his car will be fixed.

6 weeks later on 25 October , the third party called me and he mentions that his company has decducted R1000 for excess from his October pay . Now he is demanding the R1000 from me but I thought my insurance has contacted him and made arrangements to fix the car. Now he is busy haunting me and threatening me for R1000. I thought my cover is comprehensive and covers all third party damages, it doesn't make sense for me to pay the third party his R1000 if my cover is comprehensive and I am paying so much money for my insurance premiums. The third party is really stressing me out and I need answers because i will not be paying the R1000 to anyone.

Can someone please assist, I really don't need this kind of stress and I don't want any reason to leave discovery because it's been a great insurance until today.

My claim number is ***
