Hello, i was going amroli area indian post office for challan but they are not accepting and the reason is they have not working password of ojas admin side. Is this a illegal reason? If they did not able to start a system they have to contact system admin and that not big deal to get a new password from system admin. But no they told me the process take a time. I m a computer engg. I know which process take a time or not.
