Indigo Airlines — delay of flight without any intimation

Address: 360024

On 26 July 2017 i have taken a flight from Ahmadabad to Kochi Departure at 9.20 Am in IndiGo Flight. and My PNR is WIJ28U. as per the scheduled IndiGo has committed to arrive me on cochi at 13.20,
but without any prior intimation the IndiGo hostesses shifted me to the Mumbai airport and told to contact with the IndiGo Staff, We were not aware of anything is happening, anyhow we reached to the IndiGo counter in the Mumbai airport, but there were also not aware of anything after that they told to wait in the airport, after that one of the executive staff from the IndiGo has came and told that the we have to go in another flight after 7 hours.
Because of this reason i have to suffer a lost financially and physical, so i kindly requested to refund my booking amount
