MTS / Sistema Shyam TeleServices [SSTL] — there is no proper network coverage

Address:

Madurai, Tamil Nadu

I am using mts more than a years but sometimes i had a issue with mts network coverage but it recover soon. Unfortunately last 10 days network was bad and not yet recovered by mts team. And further i called customer care very poor service because call has not been connected and personally mailed this issue but still now i didn't receive a replay mail. Further i called head office regarding this issue but they infomed that in madurai there is no dealership its already closed. So i need my money back which i paid for device and also for plan i recharged on october 22nd 2017 mts number:[protected]
