Yes. They will refund your complete fee.

There is a limit set though. If you withdraw your application within the first deadline they'll take 1000 and refund the rest within the next 10–15 working days.

But if you miss the deadline they'll provide you with another deadline before which they'll refund you keeping 10000 and if you miss that deadline too, you are going to have to spend the next 4 years studying whatever course you took here
