Indane Gas Agency
Looting customers: Illegal coupons

I am a Indane customer connection no NR6231 for many years. At present my Gas Agency is UNITED GAS AGENCY, Sector -3, Rajendra Nagar, Ghaziabad, UP.

(tel no. 0120-3228251/8824, 0120-2630846)

This agency asks me to buy some coupons for delivery of Gas. These coupons are to be bought from the agency and without this gas is not delivered.

I want to know, whether this is legal? If it is not, can it be stopped?

In case, this is not the right paltform for complaints, CAN YOU PLS LET ME KNOW THE RIGHT PERSON's NAME AND TELEPHONE NO.
