Ex-Servicemen Contributory Health Scheme [Echs] — regarding non availability of medicines

Address:	Faridabad, Haryana, 121008

It's been many months since we haven't got medicines from echs. Every time we visit they say it will be available in 8-10 days.
My mother is a diabetic patient and she need to inject insulin 4 times a day and other related medicines too.
Now we have to buy it from our now.
But these are costly.
Echs is a service for ex servicemen and we are clearly not getting it properly.
Why is the medicine never available.
