Air India — Failure to reschedule flight dates

I tried to reschedule my dates of travel over 2 days before travel by repeated attempts via Air India call centre and via online chat on the website. However, every time I was told that the server is down and they could not change my dates. The Booking reference is R5LWKQ (changed from JVW0C) and e-ticket number is[protected].

I am very much frustrated and disappointed by the whole matter. The airlines should redress the issue and reimburse my costs as I shall have to buy a new ticket for my travel.
