CM no. [protected]

Today morning when I called the distributor number they immediatel arranged for the cylinder and sent it to me vide a hand written cash memo. where the booking number is different(Picture attached).Now I am worried whether I will get the subsidy or not.

Also, I tried to call the Indian Oil customer care helpline at [protected] yesterday several time but only to hear an automated voice saying the number is busy.
