Can’t open App – Navigate TestPrep: EMS Review

I downloaded the app a few days ago then last night I decided to pay for the contents, which I was charged for. Ever since buying the contents when I open the app it only stays open for about 2-3 seconds then closes completely out. I called customer service and they told me to delete the app and then to reinstall it. I did this numerous time with no success and I told the gentleman I was talking with that that did not work, his response was, “well that’s all I can tell you to do”. Terrible customer service and I have paid for something that I can not use. I am very disappointed and I will not be recommending this app to anyone in my paramedic class.
