Idea Cellular — internet offer fake

Address:

673592

I recharged for rs 392 by seeing the same on idea app.in the offer it was said they we would get 1 gb per day for 84 days
But i got only 1 gb per day for 14 days.
When i called the customer care, they said that i hadnt read the conditions of the same, but i couldn’t see any such conditions when i recharged for rs.392
Just rs 392 option was only available
