Non-responsive clients


Hi all

I have a client who ordered me and I completed the work but the client wants some of the contents exactly the same site as demo links he provided, but no content, no address, even the website he wants to build in his domain the password and the domain link of WP admin he gave me was wrong, for last three days I send messages to him knocked several times but no response. So I request the client to withdraw the Order. Today is the fifth day still no answer from the client.
Is there will be any problem to my account if the client doesn’t appear at all?
Need Expert advice Please.
