My application for registration are rejected. How i cant contact with support to check my document again? I could not contact the mederator via Comments.

 

Why did they say you already have one ?

How many mql5 accounts do you have ?

 
I have only one account - this account.
I tried to contact with Service Desk but they said "use seller request" and i could not find it

Why did you state it was a product, signal or hosting issue ?

You have to use the seller registration process.
