Bad service

I have a mobile contract with Me & You and every month I have to call and tell them that my phone says I do not have airtime. They then tell you, YOU need to tell them which contract you chose and that they now need to load the bundle onto the system. This takes 24 hrs minimum every time to do so. I cannot believe that they have all your details and then still does not know what contract you have or what service they should render.
