Consumer Redressal

I use a reliance netconnect + with a plan of 8 GB day and 15 GB night cost Rs 500/ whose billing cycle is 11th to 10th of every march. I had paid all the bills till march 2013. On Sunday which was 7th of April 2013 I got a message from reliance that my data usage is high and i have to pay 2983 Rs to enjoy continue service. i after receiving this message I called Reliance netconnect customercare where i spoke to some person at around 2 pm who told that i dont have any due and there is a maintainance work going on at Vapi station area and my services will resume art 6:00 PM after the work is over. I cheked at 8 but I was not able to connect my dongle thus i called customer care again and inquired. I spoke to zayed who told that after cheking in his special tool it shows there a mismatch of data usage as my actual usage is 5.some MB in day and 9.some MB in night which is in plan thus he took a complain and still after 3 days this is not resolved
