Spice Jet Airlines — No refund of ticket and also rude behaviour of ground staff

The SpiceJet in Bangalore airport, Didn’t answer questions properly and was using their personal mobile phones while customers queued up to ask quarries. Made my sister miss her emergency flight and wouldn’t allow refund and also charged 300 rupees to print out the ticket which was not needed to be charged as they said security would allow passage with an E-ticket and E-identity proof.
