Reliance Communications — REGARDING 3G DATA

On 13th October, 2011 i purchased a Reliance GSM SIM card of 3G data plan with submitting all the requisite documents and photographs. As per terms & conditions, with the FRC of Rs.103 the company promises to give 3 GB data in two breakups, 100 MB data is credited in customer's account at the time of activation itself and remaining data is credit within next 72 hours of activation. I received 100 MB 3G data at the same day of purchasing. However, as of now[protected] i have not received the remaining data which i m entitled to. I called up Reliance customer care several times to register my complaint. They gave me the complaint no.[protected] and ensured that it will be resolved in next 72 hours. Now the stipulated time has already elapsed but nothing has been done till now in this effect. Whenever i remind them about my inconvenience, they just ignore it by saying that "system is on upgradation, call after sometime" or "wait for some more time". I am a management student and this behavior of Reliance is very humiliating and harassing for my studies.
I, therefore, request the concerned authority to help me and do the needful. For that, i shall always owe his/her gratitude.
