Now a days there are quite a number of applicants who are not able to get an appointment slot. Getting advantage of this some people are exploiting others seeking an appointment. They are posting some alluring proposal, claiming to provide any desired slots of appointment for any PSK. These proposal can easily be found on other websites an blogs's comments areas.
One more bad thing is that some bogus person around the PSK area are offering special service for appointment. They ask an applicant to submit his original documents. And after taking ones original documents they exploit him to pay huge money. There fore its my humble suggestion that please beware of this kind of bogus people. And have patience & faith in PSK service.
I also have gone through some blogger's passport seva kendra appointment tips and tricks , but nothing is working at all. All thing which matter is perfect timing, functioning smoothness of PSK website (less traffic) and your Luck.
So have patience and keep trying your luck!!!!!!!!
