Complete unacceptable conduct

Last week Thursday night, the 14 September 2017 I took my wife and 3 year old son so this restaurant at Mall of the North in Polokwane, it was hard to convince them to have dinner at this restaurant as they both didn't feel like pizza but anyway I managed to convince then that we would have a great evening at this restaurant, upon our entry at the shop we were welcomed by a very friendly and wonderful lady who took us to our preferred table with a smile and took our order, my son then then went to the playroom to play and we set comfortably waiting for our meal. We were positioned at a table with a complete view of the play area, our meal came and as we had just started eating my son wanted to leave the play area to come to the table but was unable to do so as the gate from the playroom was difficult for him to open, he stood at the gate with no help whatsoever from the lady who is suppose to be taking care of the kids in the play area, one of the other kid's parent opened the gate for her kid and my son came out as well, out of the blue this employee of your appea and pulls my child back to the playroom, I then stoodup and went into the playroom to collect my son, upon my arrival there the lady was nowhere near the kids and one of the other kids pushed my son from the back and he hit the floor face first. Now that was a very bad experience I had as all this happened right in my face, still the lady was nowhere near the kids I literally had to pick my son up, comfort him and leave this bad restaurant, a day later the manager called me and I asked him to arrange a meeting for me with the restaurant owner which he said he would, he actually said that the owner would call me as they viewed the video and accept that the fault is on their side, now it's almost a week later and nothing has happened, I am taken for a fool and I will proof to this restaurant that I know my rights because as a black South African I am taken advantage of, I am considering legal action against this restaurant and I will not rest until this is sorted out, not because I am bitter but because I want to prevent this kind of conduct in future.
