Consumer Redressal

I have a complaint against Idea Cellular. I opted for !Plan 299 with 1 voice pack and 7 data packs in Mar14. From the first bill itself I was being charged full data usage though the usage was always within the plan limit of 935MB per month. Every time I had to take trouble to interact with Idea customer care and get the same reversed. The same thing happened in the month of July and I started getting a message that I am using data connection without a data plan. Idea customer care advised to change bill plan to overcome this problem. I did so on their website and was given communication ID C1-30763513868 on 20/08/2014. The moment this was done my data connection stopped working. I have been following up with customer care daily since then and every day I am assured that services will be restored within 24 hours. But even after 7 days services have not been restored. I am losing out on important communication due to this and have got frustrated with the approach of Idea. Please help.
