Spice Jet Airlines — insensitive treatment from cabin crew member

I had a really bad experience with spicejet. The normal flight delays are not something that usually disturbs me to the extent of raising formal complaints. However, i had a very insensitive experience from the cabin crew of sg 6353 from trivandrum to bombay dated 2 feb 2020.
Having to ask for a seat extension is not something one is proud of. I had requested one for my co-passenger very subtly as it is a sensitive matter. It was told to us by one of the cabin crew members that since we are sitting in the emergency exit, we cannot avail seat extension and my co-passenger would have to shift to another seat for landing and take off. This cabin crew member was very subtle in explaining this to us as he understood this could be a sensitive matter to certain people.
Then mr pulkit kohli who i assume to the cabin crew team lead suddenly came and he said the same thing and he was the opposite of subtle. He was very insensitive in dealing the matter and ensured the entire surrounding became aware of the issue. He was unnecessarily loud and very close to rude in explaining the same. This is something which was not at all acceptable as this is the opposite of the service we expect. I too come from a service industry and i perfectly understand how i need to deal with a customer and this was the opposite.
This led me to think, are they not trained on such matters especially how to be sensitive towards the customer as we pay for these services. This is highly disappointing and as a frequent flyer, i would like to inform that due to this disgraceful incident, you have lost two regular customers and i shall make sure i spread the news.
