Do you mean that if I want to apeal for refusal I start from the first step?

What is the reason for refusal ?

I don't know till I have not recived rejection letter.i just check the web the decision is rejet .what should I do now.?and I want to know if I appeal then how much time it's taken to get the next result

Wait for the rejection letter, read and understand what is the reason of rejection and then we can see what is the next best course of action.
