Vikas hemnani booking tkt on 12 jun from mmt for spicejet airlines from del to bangalore for 3 person for 23 jun 11:50 am flight but as soon i reached airport for chk in i was told that ur tkts has been canceled yesterday on spicejet airlines yesterday ie on 22 jun 7:16 pm and i was shocked to know that with no intimation on mail or number with that we argued and again i have to purchase a new tkt with rs 34845/- for the same flight
But the point is that they issued us the new tkt with the same pnr and as we spoke to mmt regarding this they said that only spicejet has the authority to cancel
This is totally a fraud airline that first they canceled the tkt and again they wnted to customer to purchase the tkt on higher price
I wanted to sue this airline for this type of fraud case
I wanted the detailed information abt who and from where my tkt was canceled with ip address
I request u to plz help us to solve this matter asap and wanted ur refund amt back
The details of flight and boarding pass as shared below
