1. Do what Karira has said "5. Immediately give another RTI application to the same PIO asking about what happened to the original RTI application, the complete process " etc.
2. Send a complain letter to the AA giving a step by step details on the events you have just described to us. Ask him to send you a reply within a week by FAX or email followed by a post copy.
3. File a 3rd RTI Application with the PIO of the SIC, seeking information if the SIC had advised the above PIO not to allow you to inspect on the grounds that they were "private property" etc.
4. If no response is received from the AA within 10 days, go in for Second Appeal / Complain under Section 18 & 19 of the RTI Act with the SIC.
The RTI Application at Sr. 1 & 3 above should be treated seperate cases and not mixed up with the current case, when you go in for appeal at Sr. No.4 above.
