MTS / Sistema Shyam TeleServices [SSTL] — Regarding data card service

Address:

641045

Dear sir,

This is shanmugasundaram p and i am writing this mail about how i cheated by mts. i bought my mts data card ([protected]) before 1 year. they showed me demo at my home located at coimbatore, ramanathapuram. now i changed my home near to my old address less than 1km. but i don't get proper coverage over there when i complaint about it, they said due to data traffic you won't get speed like that and they include we will responsible for data speed at demo showed address only.

But in their website http://www.mtsindia.in/coveragelocator/ they covered my area for good coverage. due to not clearing my issue i stop paying my bill. and my due amount is around rs.1400. now they call me during my office hours and disturbing me.

What i want is?
1. my initial amount paid for activation and device want to refund. (because their device is locked one so we can only use for their network only).
2. otherwise data traffic problem want to get clear.

In above two option if any think they do means, i am ready to pay my bill. please guide me in this issue sir. i request you to please reply as soon as possible.

Thanking you,
Shanmugasundram p.
