This is my response to you:
1. You can contact the Registrar of Societies: https://www.justdial.com/Hyderabad/Registrar-Of-Cooperative-Societies-Nampally/040P[deleted]N3Y1M9_BZDET ;
2. You can also call/contact the office on: http://www.telangana.gov.in/contacts/hods ;
3. The charges of 2 lakhs are too absurd, and if they are charging you that much you can send a letter according to which rule, bye-law or government circular or order are they asking for such heavy prices;
4. If they don't give satisfactory answer, then you can initiate a complaint against the society;
5. An AGM cannot decide such a heavy charge under the guise of "development charges". You can also ask for the breakdown of the charges being levied on you;
6. In the meanwhile contact the registrar's office and try to search for the guidelines or bye-laws which are charging such heavy transfer fees.
