Air India — Request for rescheduling flight not addressed by AIR INDIA

Address:

https://www.airindia.in/

I am trying to reschedule my flight of AIR INDIA, but in spite of contacting the costumer care for 16-17 times for the last 4 days and waiting for 1 hour each call, my request for rescheduling is not processed. All they do is to let me wait for around an hour and then disconnect the call in between.
Through this forum I request AIR INDIA to address my issue and resolve it as soon as possible.
