SPICEJET - PNR SG SPICEJET AIRLINE DIDNT COMMUNICATED FOR FLIGHT ITENARY CHANGES AND DIDNT ALLOWED TO BOARD FR

PNR: PF*ZPQ/ SG-Booking Ref. No: ******** Oct *th ** I bookedtickets on dated  Aug ** ** for  today’s travel i.e.  Oct *th **,  I had a Direct flight at*.** am from Hyderabad to Darbhanga,  where I have to travel with family on Dushheravacation and I reached before the travel time at *.** am via Ola taxi (Enclosed bill), I tried to get the Boarding pass however it was not allowing   forWebcheckin through machine, Infact  to get a help at  airport counter- Manager – Mr. Salman (Airport Manager and team) rejected to provideboarding pass at Airport, and told that it is already being departed via Delhi.I was not being communicated by Airline as the  manager said.
To my utter surprise neither I have not received any phone call,mail, messages regarding this Itinerary changes.
 My Mobileno. is +************ and I have not found any such kind of message, email. ( Also in the ticket wrong phone number is mentioned as ************ ( adding extra Zero and missing the last digit of my mobile number), However the travel feedback message came on the correct number which even I have not traveled to.
Apart from this,I am not able to log in through my credential to go for as forgot passwordoption which is not working. (enclosed SMS history screenshot only two messagesexcept one is related to feedback on today’s travel completion which I have nottaken journey). I requested the airport Manager, Mr. Salman, to get some alternative flight for non-communication of changed  Itinerary but he denied and said to contact customer care. Kindlyshare the delivery status for which number you communicated through SMS and emailyou delivered  along with delivery report) I feelvery much hurt and pain and faced bitter experience by the service of the Spicejet Airline as my wife and my son were ill, and have to face lot of problems resulting to book Indigo Airline Flight urgently.  I feel cheated by Airline for no communication to a valid customer.
Looking at the above, I need anapology mail/Sms, as well as a refund/credit of the amount which I have paid to Airline, where I have not traveled due to a technical glitch and negligence by Airline. If not resolved within three days, I would take this matter and forward to the appropriate authority for needful action.
Hope a quick response in this.
