Optupappphone Umber

For 4 months I have not been able to use my optup app. In the past I used it almost daily. I've contacted apple 5 times, Kroger (in store) 2 times, and cannot reach optup people. I have even taken a survey with the optup software people. I miss this app very much because it was so helpful to me. I have been told many times to talk to the optup people but I have no way of contacting them. They were extremely helpful when I first set up my app. Please, please, send me to them becauseI know that they will help me. Thank you
