Indigo Airlines — Complaint against shalini singh crm:01060023

I want to make complaint against ms. Shalini singh, terminal 1d, domestic airport delhi.
I am amazed to know from her that she is not reporting to any body.
I was in need & went to her for help. But her irresponsible & ill mannered behaviour has given me a shock.
How could be a person be so rude to the customers.
I was supposed to board the flight 6e 177 from delhi to pune @ 02:35 am on 31st july but as my train shatabdi express 12003 got delayed by 4 hrs due to issues at track. I realised i wont be able to make for 6e177 & resheduled my flight to 6e179 @ 08:15 am.
On reaching at delhi airport 1d, have simple requested to shift me in 05:15 am flight if availability is there but she replied in very bad tone and misbehaved and denied to provide any help.
Have made a telephonic complaint against her as well and want it to be recorded in the pnr pe2bgn status.
Please higlight it to the higher management and take strict actions so that such staffs won't ever behave like this with customers.
