Consumer Redressal

I have availed TATA Photon Plus post paid connection at Mahabubnagar(AP) in the month of Oct 2011 for six months subscription.While availing it was informed that in case of Prepaid migration i can recharge with RC 50 for life time validity.Presently i am residing at Nellore where there is no network coverage for TATA so i have visited Nellore outlet on 05/05/2012 for migration to Prepaid as billing starts from 12/05/12.They have denied the request and said to me that i need to visit only Mahabubnagar for the said request.I have contacted customer care as they were helpless i have approached Appellate AP-TATA.After a followup of 10 days on 16may they have said to visit the Nellore outlet for migration.They have confirmed even if i use it or not every month i need to recharge with 250Rs.Due to which i have given a request for cancellation of Connection.Today surprisingly i have received a mail from TATA to pay Rs.141 as usage charges for cancellation.Why should i pay when i have not used.Request you to take necessary action for misguiding me with wrong information.Due to which i have spent 200/- on 05/05/2012 for submission of request & my time was wasted.
