Gandhinagar, Gujarat, 382424

Me and my husband were supposed to board an indigo flight today in the morning. We were there at the airport around 6:10am and flight was at 8:40.
Since i was unwell, doctor at the aiport gave medication and told that we can board the flight now.
Lady sitting at the boarding counter refused to go for the process where we requested and convinced that we are on time. Moreover, showed the prescription. She had a word with her manager and in one go, manager asked us to proceed. We paid 2000 bucks for extra luggage, completed security check in 2mins on priority and reached main gate at 7:05 where we were again stopped for what readon we dint understand. It took us 10mins to convince the mnager who was really rude and dint understand the problem. I informed that my father is unwell and requested to let us go but he continued with his rude and stupid attitude and with no reason, dint allow us to board the flight.
Later we contacted indigo cust care where an agent named mr. Nikhil vats heard the conversation and gave us just two statements, i cant help and i am not authorised.
I asked him i[censored] knew that the gates are closed why did u charge for extra luggage nd if asked for refund, it will not be given is not acceptable. Moreover, when we completed the entire process on time as per the guidance of the indigo team, why were we not allowed to board the flight?
If it was not our mistake, there is lack of synchronisation and process knowledge, why are we paying? Do we earn to pay to indigo for no service and they are sotting to make us fool. There were many customers facing the same only with indigo. The worst airline and i faced money issue with them twice.
When asked the reasons from nikhil vats, he had no answer and when asked to process the request he said he is not authorised. I told him i myself work in service industry and have never seen somebody saying he is not authorised to drop a mail to the internal team or drop a text of email id to the customer, to talk to his manager, to take the request of refunding amount since we were not at fault. He had no answer, he could not tell our fault n could not help too.
We want the entire extra luggage amount and our ticket amount too. I would not have asked for it if would have been at fault but since we were not, we will not pay to anybody for no service and misguidance.
Improve ur system and pay our amount back.
