Loop Mobile — wrong information by customer care on Incoming call charges (national Roaming)

Address:

Mumbai Suburban, Maharashtra

Hi
I am using Loop Mobile No :[protected] since more than three years.I came to Gurgaon in October which comes in natioal roaming .
I wanted to know roaming call rates( incoming /Outgoing),so I called customer care and asked about the same ( i told executive that I am in Delhi-Gurgaon).According to customer care executive incoming calls are free.So i continued using my card.
When monthly bill come I was shocked that Incoming calls were charged ane they were around Rs.104/-.
It is all because wrong information given by customer care executive.
I want that Rs.104/- should be reversed .
Thanks !!
