Coffee burn

On the 08/10/2023 around 5:20am I went to McDonald’s in Mokopane to buy breakfast (Hashbrown and Boerie stack)so the lady who assisted me gave me a very hot coffee in a cup with a lid that was not properly closed, I tried to close the lid but it slipped and burnt my thighs which left me pain and trauma.I went to the store to report the incident and I was told that they are investigating my case but up to today they never came back to me.I reported it to head office and I was told they will transfer it to safety and security and I will receive a case number but nothing was done about it. I logged a complaint but no response. Doesn’t companies have procedures especially when it comes to incidents that happened within their premises?How can they be so ******** about the whole situation?
