Dear sir,

We have been using indane gas connection since years which is registered under my fathers name mr. Rajender singh - [protected], add. Shakti nagar delhi-110007.
Till 20117 subsidy was transferred directly to my fathers union bank a/c wherein automatically without any intimation subsidy started to get credited in hdfc a/c which is dormant now.. Have complained to the authorities nd distributor who asked to open another account so that once adhar get linked to the new account it will get disbursed in the new account... However nothing happened so far. We got new account open in bank of india (Boa) but still getting the subsidy in the dormant account hdfc...
My dad is retired and i have made more than 20 complaint to get this fixed at indane office malka ganj but they are not helping at all even saying they cant do much on this...
We as a citizen who entitle to get back the subsidy are not getting any help in change of the account... Kindly help so we don't have to make this public...
