Airtel — sms service not working both incoming and outgoing

Address:

Lane L3, Jagamohan Nagar, Khordha, Odisha, 751030

Sir I am using Airtel since last 8 year. Suddenly from last 25 days my SMS service is not working. Both incoming and outgoing service for sms is not working. I complained at call center and also I complained at the Airtel office they just ignored my complain and they are asking me to move to their postpaid service to start my SMS service. Means they are indirectly forcing me to move to post paid service which is very expensive for middle class man. Still now they are not listening to my complain. In All my bank service and entrance exams I used that number and suddenly Airtel done like this. Please somebody help me. When I asked to Port my sim they are telling me to send sms PORT number to 1900. But my SMS service is not working then how I will send SMS. [censored] Airtel. Worst service.
