Mts — The company neglected to deactivate my number and now making me face charges

Address:

Chennai, Tamil Nadu

I am Srinivasan Durai, an engineering graduating student from Tamil Nadu.i purchased mts mblaze(No:[protected]) in november of 2014. i was facing network issues from the date of purchase and i was often complaining about it to the customercare, but i dint get a proper response. So in January of 2015 i called the mts customer care and asked them to deactivate my number as i was not satisfied. but they dint deactivate my number and they have charged me for the next three months for the data i have not at all used. they have also filed a legal complaint on me. when i further contacted them they said my number was not deactivated and if i am not paying i have to face legal charges.
