I have had that happen to me too, probably they have the funds deposited beforehand and then you can talk for four hours if you want. But if you are out of funds then you can add on ten minutes twice and then you are cut off. Of course you are cut off if the psychic has an appointment.
I don't know if it has happened with others, I have noticed that sometimes when I am next in the queue, suddenly I am pushed back and there is another caller inserted, sometimes even two more clients are pushed in. It doesn't bother me much if the psychic stays logged on, but sometimes who are not online that often is really annoying. I have noticed that if you are on a call back for appointment and the connection does not go through, the customer service will try to accommodate you with in the queue, but I cannot honestly remember if they will push you ahead of other callers. At times I have had the customer service call psychics to log on back or be online for a special reading. I admit this is not with the top ones but those with average rates.
