Air India Express — Irresponsible behavior from customer care representative

My name is Dr Anoop Raveendran Nair.
I am flighing from London Heathrow to Cochin international Airport on 26/02/2022.
I called the UK customer care on-[protected] to enquire regarding the need for covid test Prior to travel.As there was a recent change in the government guidelines I wanted to know the flight company's requirement on covid test Prior to travel.I spoke to Mr Sathish Yadav and was very disappointed by his communication. He couldn't communicate to me properly in English and he had no idea about the covid test requirement asked by the airline company which I think is a very basic information.He couldn't help me with an alternative to get a response to my query.This is really a shame for the company caused by such people. So I would be grateful if I can get an update on the latest update requirement ur covid test requirement Prior to travel.
