Southern Railway — Cleanliness in train

We were travelling with kids by 16351 in coach B1. There was no cleaning done in the coach for the entire duration. We complained regarding it after a small kid defecated near the entrance and it spread inside the coach causing a bad odour. The cleaning staff at Chengalpattu behaved very badly commenting loudly if this was even a reason to call them. When we objected and pointed out the place where the kid had defecated(which by now had dried up or spread inside), they rudely said that we had complained about garbage and not potty, hence they did not get the right equipment and this is the best they could do(spraying some liquid and scraping it off). Their attitude towards the cleanliness that they are responsible for maintaining, and their way of treating passengers was extremely shocking. Basic cleanliness is all we expect and such things make us rethink if we would ever want to travel with kids by our trains again.
