Air India — itinerary

Address:

Shahjahanpur, Uttar Pradesh, 242001

Dear sir,
On dated 17.02.2019, i booked two return air tickets with air india with pnr jbsxx and ticket no 0983xxxxxx897 & 898 with both last name kasxxx for lko-del-iad (One stop at lko) for journey dated 23.05.19 and 30.10.19. On 29.04.19 i received itinerary modification amending late arrival at iad by 06 hours 25 minutes. I assume it was due to problem with pakistan air space.
Now for the journey on dated 30.10.19, i fail to hear for any change in itinerary. I wrote mails at id call. [protected]@airindia.in, call. [protected]@airindia.in, [protected]@airindia.in, [protected]@airindia.in, [protected]@airindia.in on dated 26.09.19, 28.09.19, 02.10.19, 04.10.19, 05.10.19, 06.10.19 and on 08.10.19. I tried to call them in several contact numbers. Phone is ringing and nobody is attending the call, sent emails but no reply to them as well. On dated 02.10.19, some mr. Nilesh, customer care, mumbai mailed me “xxxx can we arrange a call back on +[protected], regarding your below query. “and again, on dated 09.10.19, the same person mailed” once again we apologize for inconvenience and delay caused.” on dated 10.10.19, from call. Del, some edwin, air india customer care/ chennai mailed me “to share your updated contact number with country code, so that we can reach out to you” but no body turned up so far.
My concerns are: (I) to have a latest itinerary for journey dated 30.10.19 for flight no.104 iad-del and no 431 del-lko (Ii) while booking tickets on 17.02.19, air india provides flight del-lko, flight no 431 (Del dt 31.10.19 at 12.20 and lko 31.10.19 at 13.25) without any other option. My concern is that (Overlooking pakistan air space problem), my flight from iad will reach at del on 31.10.19 at 11.00 and with a time gap of only 01.20 hour, i have to do many exercise ; walk from plane to immigration counter, 15-20 minutes time at immigration counter, walk to luggage belt for luggage collection, walk to air india counter for boarding / luggage deposit, walk for security check and finally walk to domestic gate which is being closed 30 minutes before flight schedule (Leaving less then one hour for all aforesaid exercise). I assume but dame sure that all this could not be done during the time given and i will fail to board at the flight.
Please resolve my concern at the earliest.
Thanks
