Tata Docomo — Harassment while cancelling the Photon Connection

I have faced a serious harassment from Tata Photon for last few months. My Tata Photon Internet connection is [protected]. My request for cancellation has been raised on 18th Jun,2013 and SR #[protected]. I got a email confirmation from Mr. Rahul Shaw,Photon Care Team. He also confirmed "Also note that your connection will be disconnected by 03rd Jul 2013.". I have paid my last bill and he has confirmed it also- "Please be informed that you will not receive any further bill for the TATA". Now with a surprise I have checked the device on 29th June,2013. It's still activated. I immediately sent a mail asking for clarification. Now the next day is a shocking for me. One Ratneswar Banerjee from Phton Care Team has mailed me mentioning the wrong mobile number of mine and written "We would like to inform you that your cancellation request has been closed as you were agreed to continue with the Tata photon connection. Please be informed that your internet connection was stopped from 22nd June 2013 as you have requested to cancel the connection on 18th June 2013 and same has been activated on 29th June 2013." which is totally lie and fully opposite of Rahul Shaw's version. I called several times of customer care and they obviously can't help. As per customer care they are again generating a bill. This is too much. These Tata Photon people are cheating people with there anti-customer policy and continuous harassment all together. This is my first step to raise this harassment of Tata Photon in consumer forum. If nothing happens I will seriously think taking legal action against these Tata Photon customer care.
