EaseMyTrip.com — Not willing to delete my account

I have asked EaseMyTrip three times to delete my account. They write back and deliberately ignore my request, offering to change my communciation settings or similar rather than actually delete the account. I am uhappy with this company and do not wish to use their service ever again - as such, I would like them to fully delete my account and put my data beyond use. This is a legal obligation for the company. The account must be deleted, fully, and be completely inaccessbile. Please comply.
