Consumer Redressal

I am a MTS data card customer. My MTS #: 8925974937 I purchased the data card on Apr 2014. It was working good until 08 Sep 2014. I lost connectivity from 8 Sep 2014. I complained to MTS customer care. Complain #: SEP/3135. No reply from customer care. They just told me to wait for 48 hours again and again. I appealed for Appellate after 7 days. They told, they switched off the tower. No more service in my area. Is this allowed practice as per TRAI regulation? They installed tower an year back and run it for one year. Me and my friends purchased MTS data cards. After that they closed their service without any intimation. Please control this type of unprofessional behavior with customers.
