Consumer Redressal

I had registered for a complaint on 20/12/2014 with regard to my 3g Data Plan in my red Business plan 999. According to my plan I am supposed to get 4gb of 3G Data but for last few month I have been getting only 1 gab of data in 3g speed and post that I go on to 64 kips speed. I spoke to customer care on 20 the December and I was told I will get a call back by the end of the day with regard to the status. No one called me back and I spoke to floor supervisor on the same day evening who had promised the issue will be rectified by the technical team by 22nd December 2014Monday morning. I am trying to reach out to guys several times on the 198 number and it say unable to process your request. They have barred me on customer care complaint number as well I am a customer who has been using your service for more than 2.5 years.
