I’ve had this experience before and i would recommend following the call script as although referred by a good friend of mine. The potential client went elsewhere after an initial meeting going over their project. However i found that they had taken some information they never knew and my guess ran with it elsewhere.
But if i had followed up with the call script that advice i gave them, i would have charged them the $795 Low Commitment fee as suggested by Enoch and would not have wasted time and money.
Hope this helps!
