Idea Cellular — cheating the consumer

Retailer in my town cheating customers by giving half information about plans,
I ans my friend hv port our sim from telenor to idea. Retailer said that rs 300 plan gives me 84 days unlimited talk time, but after one month my plan was expired. We contacted in his office he is saying that offer is only for 28 days...
And behaving in rash manner very neglect answers.
Is this the way to behave with the customer..
Take action on idea dealer immediately. Other wise idea will loose a loage number of customers in our town
