Kindly post us the full details of your RTI application--to whom it was addressed and what were the details of information sought. Also inform us, the contents of the letter that you received from the surveyor and also the tashildar. I find certain missing links in your narration.
Besides, there is no need for you to chase the surveyor next month. Since you have already taken the RTI route, complete the full course of that route(if it becomes necessary) by taking it to its logical conclusion.
