Confuse about Oral test

Hello

I applied for my oral test online
And they sent me a code and a date to go to caserne which is 17 oct.

I went to caserne today and they asked me to pay rs500 for the test
Took 2 photo of mine
And filled a form

And they asked me to go home

Without doing the test and they kept the receipt.

Can anybody explain me what should i do next
Am really confuse
