MTS / Sistema Shyam TeleServices [SSTL] — Mts not disconnecting my mts mblaze postpaid connection

Address:

New Delhi, Delhi, 110008

I have used mts postpaid connection for over a year and due to not being satisfied with their service, i had called the customer care on 15/03/2016 for deactivation as the bill cycle starts on 16th. I had also settled my dues for the period 16/02/2016 to 15/03/2016 even before the bill was raised for the period.The customer care guy said he is has taken this request and i will receive the call from the retention department within 3 business days confirming the same. I did not receive any calls regarding it. I received the bill for the period 16/03/2016 to 15/04/201 despite my request for disconnection of the same. I called the mts customer care again and the customer care guy said he has taken my query and i will received a call within 3 business days regarding the issue. Till now i have not received any call for it. Despite my calls they are not disconnecting the connection and calling again and again for the bill. I have told them several times that i had not used the service but they are calling again and again and harassing me to pay the bill. They are not even bothered to reply back or answer me regarding the request made by me for the disconnection. Nonetheless, i won’t be paying their bill as i didn't use their service.
