Worse customer service I ever experienced

On the 25/02/2023 I've put in R300 petrol in my car @ Engen Forest Drive Auto. While the petrol attended was busy putting in the petrol, another attendee broke my car light by accident. I reported to the cashier and she said they will sort it out I just need to get the quote. After three days of me trying to get an quote (because the part is discontinued) i finally got the quote and took it to service station (Engen Forest Drive). The manager at the service station than told me that they've look at the cameras and saw the incident and they will sort everything out I just need to email the quote with photos of the damaged light to them and they'll come back. After two months of no feedback from them and me calling them on several occasions I reported the incident to Engen Petroleum Head office(on the 1st of May 2023). They told me because it's an public holiday that some will come back to me the next day. Next few day and nobody called back and I've call again on several occasions. The last time I've phone them I asked to talk to the person who is handling the incident and was told that the lady was busy and the she would call me back ASAP. I'm deeply dissatisfied with the service or at least feedback from Engen. Anyone that can assist me or tell me what's the next thing I can do?
