My Tata Docomo Number Land line no.[protected] in my name
Shubhro Roy. The telephone set is out of order since January 2013.I have paid rent up to Nov 2012. On January I informed the company that the set is out of order ,so please replace the set with a new one. They have informed me to go to their Park St. Kolkata Outlet and they will repaire it. I went there in Feb 2013 for reparing the set but they urged me to buy a new set.for Rs.2500.There is nothing in my contract at the time of taking connection that I shall have to take a new set by paying the price when my old set is out of order.I also told them at the outlet to repaire my old set but they declined. since then the set is out of order but the company also charged the calls for January 2013, which actually I did not use and also the rent charges and now demanding Rs.1259.00 and threatening to take action.I again humbly request the company to repair or exchange the set and then the matter will be negotiated.
