Jet Airways — compensation on baggage damage not received for reacted

Address:	Mumbai City, Maharashtra, 400099
Website:	www.jetairways.com

I have been claiming about the baggage damage on arrival to heathrow airport from last week 19th sep. I have called over 10 times to jet airways london office, and they told me to email ([protected]@jetairways.com) which i did not have any response, and i called again and was told to email another ([protected]@jetairways.com). Now i do not have any answer from both emails, and london office do not take their phone.
I have been using jet airways several times, and are depressed of this attitude. Can you urgently address below issue? Below are the email i've sent.

This is naoko takahashi, japanese who currently live in uk.
Please let me report the damage on my baggage as attached photos.

- damage : out of the 4 wheels, 2 wheels were totally gone away, when i picked up my baggage in heathrow airport.
- date : 19th sep 2018, around 7:00 am
- place : heathrow airport terminal 4
- flight of arrival : 9w120 (Mumbai 1:40 to london 6:45)
- flight of check in : 9w4143 (Narita 11:45 to mumbai)
- status of my suitcase : it was very new, and first time to use. I bought it in japan sep 2018.
- losses : my suitcase is no longer usable, and i had to take the taxi from heathrow which costed £120.

As the suitcase was brand new and first time to use, i do understand that this is damaged caused by the flight, please kindly assist in recourse /compensation and also for the taxi fee.
I understand that the airline is liable for damages under the montreal convention 1999.
So, could you please advise me for further procedure for this case?

Thank you very much and very much appreciate your understanding, and hear from you soon.
