In a Mediumship Reading, I make sure there is no doubt in your mind that the spirits I am in contact with are definitely your loved ones on the other side. I do this by sharing concrete evidence and detailed information that you are able to validate. They will come though with names, their personalities, items and memories you will recognize.
I can't promise that the specific person you are trying to reach is going to come through. No one can. I can't make anyone show up on command. You may hear from spirits other than the ones you are hoping to connect with and you may have surprise visitors as well that you weren't expecting. I will say that most of the time the people you do want to connect with do come through.
