You can ask for the date of forwarding of your applications along with a copy of AWB/receipt of redg or speed post, date of receipt in the o/o Chairman Ramadoss, Copy of POD, and copy of reminders if any and copy of reply if any.
If there is no reply then what action should have been taken as per rules and what action was taken?
How can an employee of the company defy the orders/advice/instructions of his superior authority, or member from Govt. on board, even if he/she is a Chairman and interestingly in your case Ramadoss is blamed for corruption?
You and Govt./ministry can ask the acting Chairman to reply.
Even if Ramadoss is instructed to be out of office and new chairman might have recently joined or may assigned to two companies, GM (P) and Krishna and others who are custodians of the information are still in the company.
You need to persue.
