On the embassy website is the link for the appointment. I suggest to do the pick up appointment in advance as u also need an appointment for that. Because you will need a phone number to get both appointments.
So like what i did was:went to the link to get the appointment for dropping the documents. And then you click on get a new ticket. Then it shows you the option of visa collecting. And just choose the time for your appointment. Thank god i did that because my phone wasnt working in kl.
