Consumer Redressal

I have been asking to cancel my request since past two months. I have raised around three requests now and have no satisfactory response infact I lost all the respect and interest in Tata Photon services after experiencing this kind of inefficient staff and concern towards the customers. Every time i raise a cancellation request they will say the request is raised and cancellation will occur after 7days and after around 10 days a new person will be calling and will say a new offer is awaitng for you and please avail it and when i say my device is already cancelled and i got a message they will reply that..NO NO NO...Its in active state and you have accepted to retain it... I cant use vulgar language here and my anger has gone beyond limits after this kind of response..
