SMS service is useless we paid 300 for 3 files but got no updates about passport curier tracking number. I had to call customer care for details than why they took 300 for sms service ?? And it took 4days to reach our passports and curier fee for that is RS 300 per passport which is for express delivery but delivered after 4 days of disodisp from embassy.
