For any complaints please register same on https://pgportal.gov.in/(this is a ministry portal). Lodge the complaint against Telecommunication -> Dept. of Telecom mentioning Tikona in service provider name. The ministry people will help get it sorted out.
I have found it out after months of writing to different people and ministries, raising it on different consumer forums. The above mentioned one is the only govt. forum which is tracked and responded to properly. So let us make a better use of platform provided to us by Ministry and avoid endless calling to service provider.
