In my early days of psychics I would never call the psychic back again if they told me what I didn't want to hear. I also left negative feedback because I thought they weren't connected. I don't do that anymore. If they told me what I wanted to hear I'd maybe leave positive feedback, but more importantly I would call them again to find out how things are coming along and why contact didn't happen etc.
These days, if I don't get any valid information that the psychic can read me after 3 minutes I hang up. Most good psychics will want you to not say much, so that they can gain your trust by showing you their gift, then you ask your questions. I'm fine with birthdays, as it gives me something to say so they can connect to my voice. Yana has you talk about the weather or the time.
