GoAir — Mandatory payment for each seat during web check in

Address:

Gurgaon

I have booked Go air flight for my journey on 28th Dec 2020 from Goa to Lucknow with change of flight at Mumbai.
On 27th when I tried to web check in as a mandatory requirement during Covid, the site was asking about Rs 1150 for web checking charges.
This was not the condition while booking but when spoke to Go air tele executive on 28th morning at about 09:30 she said this is mandatory and passenger have to pay.
I was reluctant to pay and ultimately missed the flight just to remember for the life and another 1000 how unethical Go airways. The executive also informed me since you have booked from Make my trip, it was their responsibility to inform.

My PNR: R5VUHS flight on 28th Dec. name of passenger Abhigyaan Mohanty
