Emirates not taking Responsibility for their Service

Emirates flight EK761 from Dubai to Johannesburg landed at 11:25, one hour later than scheduled as a result I missed my connecting flight via Safair from Johannesburg to Durban on 06 Jan 2024. (Booking Ref HXCX4F). We informed the Emirates ground crew who did not take responsibility for the delay and for my inconvenience. I had to purchase 2 tickets from Safair (Booking *** costing me R 2348,88). Upon arrival, a day or two later I communicated with Emirates via their chatbot and was informed by this machine that I had to inform Travelstart who were my booking agent.) I contacted Travelstart via their online app and to date have not received any response or reply. Emirates caused the boo boo why are they shifting their responsibility and giving us, customers the run around. Emirates needs to take responsibility for their negligence in this matter.
