I sent it to them via post & received the approval letter the following week.
All good except they didn't return my Indian passport !!
I submitted an online query last week asking them to return my passport as I need it for my India travel due on 07th December.
I received a letter from them today saying as per their records my Indian passport is recorded lost/stolen since April 2015 hence they have had to send it to the local Indian embassy and any further correspondence on this should be done with them!!!!
I am at my wits end

please could anyone suggest what's the best approach here as I have less than 3 weeks left for my travel..?
a) Should I go to HCI, London or CGI,Birmingham (as I live in West Midlands)..?
b) Will they entertain such a query..do I need to speak to anyone in particular?
c) In the worst case, will they be able to issue an emergency travel certificate to me?
Please !! looking for some suggestions asap.
Many thanks.
