Shosholoza Meyl Train Derail

Good day. I trust the all is well. I would like to lodge a formal complaint with regards to the service received on the Shosholoza Meyl train that derailed on Friday 05 July 2019. I was on the train on Friday evening when the train derailed on Friday evening at 22:00. Till now there has been no communication from anyone with regards to what happened. Once the train derailed we revived no communication as to the problem or solution unless we got off the train and went looking for the train manager or people working on the train. I was on the 1st setter coach after the diner, my coached back wheels had derailed, we received no medical treatment on the site. I am now suffering with my lower back and hips after the impact, my 20month old son is not sleeping properly after the accident. The medical team and fire department only arrived on site at 12:00 and only the people in 1st class were seen. No-one in economy class were seen. The additional transportation that was supp**** was busses that had no toilets on, so we had to hope that the bus would stop somewhere that there was a toilet. The busses only arrived on site at 08:00 on Saturday morning 06-07-2019, we ended up sleeping on the floor in the middle of nowhere. I feel that this is unacceptable and would like to know the cause of the accident as well as information that is needed to report my injury.
