GoAir — name change request on the same day just after booking

Address:

Thane, Maharashtra, 400612

I mistakenly put incorrect name for one of the co passenger. And immediately I wrote to the customer care email id requesting to correct the mistake but have not got any reply yet. request number : G[protected]
I also requested my brother to talk to your customer care. But they said nothing can be done from your end. This is my first travel with go air and this kind of service is being given?
