Idea Cellular — Sale of same service at two different cost.

Address:

Thane, Maharashtra, 421004

Dear sir,

My name is prashant patki and my contact number is [protected]. I recharged the mobile by rs 301 from my last recharge which expired today. I received benefit of only 1 gb data but not the unlimited calling service. Now, your customer care executives ms. Arti jadhav telling me that we are offering the same benefits at two different cost. Isn't it illegal to sale same service at two different cost in india?
