I am using reliance post paid since last 3 yrs and was using plan in which reliance to reliance phone calls were unlimited free. Till last month I was receiving normal bill (rental and other call charges). Suddenly yesterday I received a huge bill for last month. On calling at customer I was told that the facility of reliance to reliance free call service was withdrawn on 15 August with few exceptions and so all the calls made on reliance number are charged after 15 August'09. On telling that why they didn't inform customers about withdrwing this services? How can they withdraw any chargable services without giving notice or informing customer , they are not able to answer and still not taking any action on my bill. I am really very upset with the huge amount of bill I am liable to pay for the reason that reliance mobile didn't inform me for closing that plan partially. Please suggest where I can approach or lodge complaint again it?
